NAME

     xxxterm — lightweight web browser

SYNOPSIS

     xxxterm [-nSTtV] [-f file] [-s session_name] [url ...]

DESCRIPTION

     xxxterm is a minimalistic web browser that tries to stay out of the way so that valuable
     screen real estate can be used for much more important stuff.  It has sane defaults and does
     not require one to learn a language to do any configuration.  It was written by hackers for
     hackers and it strives to be small, compact, and fast.

     xxxterm is very simple in its use.  Most actions are initiated via key or mouse bindings.
     Key bindings are based on those of the vi(1) text editor, giving web browsing a similar feel
     to navigating a text document.  The KEY BINDINGS section below documents the various
     defaults and possible customizations.

     The options are as follows:

     -f file
             Specify an alternative configuration file.

     -n      Open a new tab in a running xxxterm for each specified URL.  This option requires
             enable_socket to be enabled.

     -e command
             Execute arbitrary command (see the COMMAND MODE section below) in a running xxxterm
             instance. This option requires enable_socket to be enabled. Example run: xxxterm -e
             "tabnew openbsd.org"; xxxterm -e tabclose; xxxterm -e wq.

     -S      Disable the toolbar.

     -s session_name
             Open session that was saved with ":session save" command.

     -T      Disable visualization of tabs.

     -t      Disable tabs.

     -V      Display version and exit.

FAST STARTUP

     The following notation is used throughout this page:

           C-      Control
           S-      Shift
           M1-     Meta 1 (sometimes marked Alt)
           M2-     Meta 2
           M3-     Meta 3
           M4-     Meta 4 (sometimes marked Windows)
           M5-     Meta 2
           MB1     Mouse button 1

     To browse to a specific address, either use the mouse to click on the address bar or press
     F6 to shift the keyboard focus to the address bar.  The address is then entered manually.

     The mouse can be used to navigate the page in the traditional manner, or the keyboard can be
     used instead.  For example, PageUp and PageDown will scroll up and down the page.

     To follow a link, either click on it or use the f key and have xxxterm assign numbers to
     each link on the page; entering that number on the keyboard will prompt xxxterm to follow
     the link.

KEY BINDINGS

     xxxterm provides many actions accessed via key or mouse bindings.  Most can be reprogrammed
     using a keybinding entry in the configuration file.  Each keyboard shortcut requires exactly
     one entry in the configuration file.  A shortcut can have multiple entries in the
     configuration file.  The format of the keybinding entry is as follows:

           keybinding = action,(!)keystroke(s)

     For example, "keybinding = tabnew,C-t" where tabnew is the action and C-t are the
     keystrokes.  GTK has some default keybindings for manipulating text inside input fields,
     such as the URI or search entry widget, for example C-w deletes a word. To override these
     defaults prefix your key with an exclamation mark, like this: "keybinding = tabclose,!C-w".
     The clearall key word is special and is meant to reset the key binding list to the GTK+ and
     WebKit defaults.  This keyword should be the first keybinding entry in the configuration
     file.

     Shift should be used sparingly since it gets in the way of non-USA keyboards.  See the
     accompanying configuration file for examples.

     The various bindings are documented below.  The relevant keybinding action is given
     afterwards, in parentheses.

   Command mode
     These commands are used to focus or unfocus input on the default input of a web page.

           ESC     Go to command mode; unfocus current entry on web page.  (command_mode)

   Tab Manipulation
     xxxterm supports tabbed browsing.  That is, web pages may be opened in separate tabs,
     allowing the user to quickly move from one page to another, and back.  These commands then
     are used to create, destroy, and move between tabs.

           C-MB1               Open new tab with the clicked link
           C-t                 Create new tab with focus in URL entry (tabnew)

     number to follow the link.  Alternatively one can type the name of the link and when there
     are no more possibilities xxxterm will follow the link.

           f, '.'  Highlight all links and prefix them with a number.  (hinting)
           F, ','  Highlight all links and prefix them with a number but open in a new tab.

           session, session show
                   Display the current session name.  By default the session name is
                   main_session.  To create a new session use the session save command.  A
                   session is defined as the lifetime of the browser application.

           session delete <session_name>
                   Delete session session_name from persistent storage.  If session_name is the
                   current session then the session will revert to main_session.

           session open <session_name>
                   Open session_name and close all currently open tabs.  Going forward this
                   session is named session_name.

           session save <session_name>
                   Save current tabs to session_name session.  This will close the current
                   session and going forward this session is named session_name.

           set     The set command is used to inspect, clear or change runtime options.  There
                   are 3 methods to use :set.  When used by itself as :set the command displays
                   all options as currently set.

                   To set a value use :set option=value.  For example, :set
                   http_proxy=http://127.0.0.1:8080.

                   To clear a value use :set option=.  For example, :set http_proxy=.

                   Note, not all options can be set at runtime.

           stats   Show blocked cookie statistics.  These statistics vary based on settings and

                   session is opened.  See the session command for additional details.

           wq      Save open tabs and quit.  The tabs will be restored next time xxxterm the
                   session is opened.  See the session command for additional details.

BUFFER COMMANDS

     In addition to shortcuts and commands xxxterm provides buffer commands. Buffer commands are
     short, multi character vi-like commands, often requiring an argument. Partial buffer
     commands are displayed in the buffer command statusbar element (see statusbar_elems).
     Pressing Esc or switching to another tab cancels a partially entered buffer command. In the
     following list arg denotes the argument a buffer command accepts. Buffer commands are
     defined as extended regular experssions.  Note that if a character is used as a shortcut it
     will not be interpreted as the beginning of a buffer command. This is the case with 0.

           gg                 go to the top of the page
           gG                 go to the bottom of the page
           [0-9]+%            go to the arg percent of the page
           zz                 go to 50% of the page
           [0-9]*gu           go arg levels up. If arg is missing, 1 is assumed. Going a level up
                              means going to a URI obtained from the current one by removing the
                              last slash ('/') character and everything that follows it
           gU                 go to the root level, i.e. going up as many levels as possible.
           gh                 open the home page in the current tab
           m[a-zA-Z0-9]       set a mark denoted by arg at the current page position. These marks
                              behave like those in vi or less.
           ['][a-zA-Z0-9]     go to the position where mark arg was set
           M[a-zA-Z0-9]       set the current uri as quickmark arg
           go[a-zA-Z0-9]      open the uri marked as quickmark arg in the current tab
           gn[a-zA-Z0-9]      open the uri marked as quickmark arg in a new tab

QUICKMARKS

     Quickmarks are like bookmarks, except they are refered to by a single character (a letter or
     a digit), instead of a longer name. See the M[a-zA-Z0-9], go[a-zA-Z0-9] and gn[a-zA-Z0-9]
     buffer commands for usage. Quickmarks are stored in ~/.xxxterm/quickmarks and are saved
     automatically after each M[a-zA-Z0-9] buffer command.

ABOUT SCREENS

     The about screens are internally generated web pages by xxxterm for user interaction.  These
     are entered in the address bar and the format is about:screen where screen is the desired
     screen to display.  For example about:favorites.  Any about screen can be used as the home
     page as specified by home in the configuration file.

           about         show the about screen
           blank         show a blank screen

WHITELISTS

     This section describes advanced usage settings.  Most users should use browser_mode instead
     to setup xxxterm and skip over this section.

     xxxterm has a number of whitelists to control blocking cookies and Java Script execution for
     FQDNs or domains.  When properly enabled these whitelists require either the FQDN or top
     level domain to exist in the whitelists in order to allow cookies to be stored or Java
     Script to execute.  Both Java Script and cookies have two whitelists associated with them.
     The whitelists are called session and persistent.  Items in the session whitelists are only
     allowed for the lifetime of the xxxterm instance.  Items in the persistent whitelists are
     stored on disk and are restored upon restarting.

     Setting up the whitelists is a little tricky due to intricacies of WebKit.  In fact the
     semantics are different for cookies and Java Script.

     Cookie whitelist requires the following configuration to be set:

           cookies_enabled             This is a WebKit setting and must be set to 1 (ENABLED) in
                                       order to be able to use a cookie whitelist.
           enable_cookie_whitelist     This needs to be set to 1 to enable the cookie whitelist
                                       functionality.
           cookie_wl                   These entries in the configuration file are the actual
                                       domains names in the cookie whitelist.

     Java Script whitelist requires the following configuration to be set:

           enable_scripts          This is a WebKit setting and must be set to 0 (DISABLED) in
                                   order to be able to use a Java Script whitelist.
           enable_js_whitelist     This needs to be set to 1 to enable the Java Script whitelist
                                   functionality.
           js_wl                   These entries in the configuration file are the actual domains
                                   names in the Java Script whitelist.

     Plugin whitelist requires the following configuration to be set:

           enable_plugins              This is a WebKit setting and must be set to 1 (ENABLED) in
                                       order to be able to use a plugin whitelist.
           enable_plugin_whitelist     This needs to be set to 1 to enable the plugin whitelist
                                       functionality.
           pl_wl                       These entries in the configuration file are the actual
                                       domains names in the plugin whitelist.

     See the FILES section for additional configuration file entries and details that alter
     runtime behavior.

FILES

     ~/.xxxterm.conf       xxxterm user specific settings.
     ~/.xxxterm            xxxterm scratch directory.

     xxxterm tries to open the user specific file, ~/.xxxterm.conf.  If that file is unavailable,
     it then uses built-in defaults.

     The format of the file is <keyword> = <setting>.  For example:

           http_proxy = http://127.0.0.1:8080

     Enabling or disabling an option is done by using 1 or 0 respectively.

     The file supports the following keywords:

           alias                       Defines an alias for a given URL, so that the URL is
                                       loaded when the alias is entered in the address bar.  If
                                       the aliased URL includes a %s format specifier, then any
                                       argument given after the alias on the address bar is
                                       substituted.  For example, if
                                       g,http://www.google.com/search?q=%s is defined as an
                                       alias, then the URL http://www.google.com/search?q=foo is
                                       loaded when navigating to "g foo".
           allow_volatile_cookies      If set cookies are stored in the session cache but will be
                                       discarded once xxxterm exits.  Unfortunately enabling this
                                       does allow for some limited tracking on the web.
           append_next                 When set a new tab is appended after the current tab
                                       instead of being appended as the last tab.
           auto_load_images            If disabled, images will not be loaded automatically.
           autofocus_onload            When set a tab that is loaded will attempt to autofocus
                                       the default input entry.  This is only done for tabs that
                                       are currently visible.
           browser_mode                The xxxterm browser has 3 default operating modes: normal
                                       (the default), whitelist and kiosk.  In the normal mode
                                       the browser allows all cookies, plugins and Java Script as
                                       any other browser would.  This means that all cookies are
                                       saved to persistent storage and that all Java Script and
                                       plugins run.

                                       On the other hand, using the whitelist mode enables
                                       whitelists.  This requires the user to add all the
                                       required cookie_wl, js_wl and pl_wl items.  If a domain
                                       does not appear in the whitelists xxxterm disallows
                                       cookies, Java Script and plugin execution.

                                       In kiosk mode the browse works just like normal mode
                                       however the toolbar only has the backward, forward and
                                       home button.

                                       This setting must be the first entry in ~/.xxxterm.conf
                                       because it sets advanced settings that can be overridden
                                       later in the file.  See the default config file for more
                                       details.
           cmd_font                    Set the command prompt font.  E.g.  cmd_font = monospace
                                       normal 9.
           color_visited_uris          When enabled (the default) xxxterm will color visited
                                       links. This is done while the web page loads using
                                       JavaScript, rather than WebKit's (broken, see bug #51747)
                                       built-in facility for coloring visited links. The
                                       JavaScript approach is (probably) slower and is not
                                       consistent across tabs (unless the tabs are reloaded), but
                                       has the advantage of not leaking history data to web pages
                                       (see http://wtikay.com/docs/details.html).
           cookie_policy               This field delineates the cookie policy.  Possible values
                                       are: no3rdparty, reject 3rd party cookies.  accept, accept
                                       all cookies.  reject, reject all cookies.
           cookie_wl                   This is a cookie whitelist item.  Use multiple times to
                                       add multiple entries.  Valid entries are for example
                                       *.moo.com and the equivalent .moo.com.  A fully qualified
                                       host is also valid and is for example www.moo.com.
           cookies_enabled             Enable cookies.
           ctrl_click_focus            Give focus in newly created tab instead of opening it in
                                       the background.
           default_script              Path to the script used as the default value for the
                                       run_script command.
           default_zoom_level          Set the default browsing zoom level.
           download_dir                Locations where files are downloaded to.  This directory
                                       must exist and xxxterm validates that during startup.
           download_mode               Controls how downloads are handled.  Possible values are:

                                             start - automatically start download.
                                             ask   - ask user for confirmation.
                                             add   - add to downloadmanager, but
                                                     do not start.
                                       The default is "start".
           enable_autoscroll           When enabled clicking MB3 will spawn the autoscroll ball,
                                       scrolling can then proceed by dragging the mouse away from
                                       the ball.
           enable_cookie_whitelist     When enabled all cookies must be in the whitelist or they
                                       are rejected.  Additionally whitelisted cookies also
                                       enable HTML5 local storage for the domain.
           enable_favicon_entry        When enabled (the default) xxxterm displays the favicon of
                                       the web page at the URI entry. This setting affects both
                                       normal and compact tabs.
           enable_favicon_tabs         When enabled (disabled by default) xxxterm displays
                                       favicons at each tab. This setting only affects compact
                                       tabs.
           enable_js_whitelist         When enabled all domains must be in the js whitelist in
                                       order to run Java Script.  NOTE: Make sure enable_scripts
                                       is set to 0.
           enable_plugin_whitelist     When enabled all domains must be in the plugin whitelist
                                       in order to run plugins.  NOTE: Make sure enable_plugins
                                       is set to 0.
           enable_plugins              Enable external plugins such as Flash and Java.
           enable_strict_transport     Enable support for the Strict-Transport-Security HTTP-
                                       header.  When enabled, sites that set this flag will only
                                       be visited via HTTPS.  Default value is 1
           enable_scripts              Enable Java Script.
           enable_socket               When enabled the first instance of xxxterm will create a
                                       socket in the ~/.xxxterm directory.  Using the -n url
                                       option on subsequent xxxterm invocations will cause the
                                       specified URL to be loaded in a new tab.  Only a user with
                                       identical UID and GID can use this option.
           enable_localstorage         Enable html5 Local Storage.
           enable_spell_checking       Enables spell checking. Preferred languages can be set
                                       using spell_check_languages option.
           encoding                    Set the default encoding.  E.g.  encoding = ISO-8859-1.
           external_editor             Set which editor to use for external editing.  the string
                                       <file> will be replaced by the current filename.  E.g.
                                       external_editor = gvim -f <file> Note!  xxxterm relies on
                                       the editor not forking into the background.
           fancy_bar                   Enables a backward, forward, and stop button to the
                                       toolbar.  Additionally if search_string is set it'll
                                       enable an entry box for searches.
           guess_search                When enabled xxxterm will try to guess if the string you
                                       entered, in the URI entry widget or the command widget, is
                                       term you want to search for using search_string (see
                                       above).  If the string does not contain a dot nor a slash,
                                       is not a path to a local file and does not resolves to an
                                       IP then it is assumed to be a search term.
           gui_mode                    To simplify configuring xxxterm allows you pick between
                                       two GUI modes: classic (the default) and minimal.  In the
                                       classic mode the GUI looks similar to that of most
                                       mainstream browsers. While in minimal mode the GUI looks
                                       more vi-like. One can get a GUI between the two by
                                       tweaking the low-level GUI settings found under the
                                       advanced GUI setting section in the configuration file.
           history_autosave            When enabled xxxterm will save all command and search
                                       history.  Upon restarting xxxterm the saved command and
                                       search history will be restored.
           home                        Homepage in URL format.
           http_proxy                  Proxy server in URL format.  xxxterm overrides http_proxy
                                       if it is specified as an environment variable.  It must be
                                       noted that on older webkit versions one MUST use an IP
                                       address and not a FQDN.  This works as expected with
                                       webkit 1.4.2.

                                       If one desires to use a socks proxy then an intermediary
                                       tool must be used.  It has been reported that tsocks works
                                       with xxxterm.
           icon_size                   Permits icon sizes to be changed if fancy_bar is enabled.
                                       Size 1 is small; 2 is normal; 3 through 6 are
                                       progressively larger.
           js_wl                       This is a Java Script whitelist item.  See cookie_wl for
                                       semantics and more details.
           max_connections             The maximum number of connections that xxxterm can open at
                                       once.
           max_host_connections        The maximum number of connections that xxxterm can open at
                                       once to a given host.
           mime_type                   Sets an action for a specific or default MIME type.  For
                                       example, to download and view a pdf using kpdf set
                                       mime_type = application/pdf,kpdf.  To set a default value
                                       use *, for example, mime_type = video/*,mplayer.  Note
                                       that the action is only passed the URL and not all
                                       applications are capable of dealing with a URL and
                                       therefore one might have to create a wrapper script to
                                       download the content first.  Alternatively one can add the
                                       @ in front of the MIME type to indicate "download first".
                                       For example, mime_type = @application/pdf,xpdf.  When @ is
                                       use the file will be downloaded to the download_dir before
                                       the MIME handler is called.
           oops_font                   Set the font used to display error messages.  E.g.
                                       oops_font = monospace normal 9.
           pl_wl                       This is a plugin whitelist item.  See cookie_wl for
                                       semantics and more details.
           read_only_cookies           Mark cookies file read-only and discard all cookies once
                                       the session is terminated.
           refresh_interval            Refresh interval while in the download manager.  The
                                       default is 10.
           referer                     Control how 'Referer' is handled in http-requests.

                                             always      - always send referer
                                             never       - never send referer
                                             same-domain - only send referer if it's
                                                           for the same domain
                                       Any other value that is also a valid URL will use this
                                       custom value as referer. (E.g. you could set it to
                                       http://no-referer.com) The default value is "always"
           resource_dir                Directory that contains various xxxterm resources such as
                                       icons.  This is OS-specific and should be handled by the
                                       porter.
           save_global_history         If set the global history will be saved to
                                       ~/.xxxterm/history when quitting and restored at startup.
                                       See the KEY BINDINGS section above for how the global
                                       history is accessed.  Global history is not saved to disk
                                       by default.
           save_rejected_cookies       Saves rejected cookies in cookie format in
                                       {work_dir}/rejected.txt.  All cookies are saved and unlike
                                       a cookie jar they are never replaced.  Make sure there is
                                       enough disk space to enable this feature.
           search_string               Default search engine string.  See the xxxterm.conf file
                                       for details.
           session_autosave            Enable session auto-saving when changing state (e.g.
                                       adding or removing a tab).  The session name is what is
                                       currently in use and is described in the session save and
                                       session open commands.
           session_timeout             This value is the time that is added in seconds to a
                                       session cookie.
           show_tabs                   Enable or disable showing tabs.
           show_url                    Enable or disable showing the url and toolbar.
           show_statusbar              Enable or disable showing the status bar.
           single_instance             If set and enable_socket is enabled only one xxxterm will
                                       be permitted to run.  If there is a URL specified it will
                                       be opened in a new tab in the already running xxxterm
                                       session.
           spell_check_languages       The languages to be used for spell checking, separated by
                                       commas. For example, en_US.
           ssl_ca_file                 If set to a valid PEM file all server certificates will be
                                       validated against it.  The URL bar will be colored green
                                       (or blue when saved ) when the certificate is trusted and
                                       yellow when untrusted.

                                       If ssl_ca_file is not set then the URL bar will color all
                                       HTTPS connections red.

                                       WebKit only supports a single PEM file.  Many OS' or
                                       distributions have many PEM files.  One can simply
                                       concatenate all separate files into one large one.  E.g.
                                       for i in `ls`; do cat $i >> cert.pem; done and use the
                                       resulting cert.pem file as the input to ssl_ca_file.  It
                                       is advisable to periodically recreate the cert.pem file.
           ssl_strict_certs            If this value is set connections to untrusted sites will
                                       be aborted.  This value is only used if ssl_ca_file is
                                       set.
           statusbar_elems             Define the components of the status bar. The possible
                                       components are:

                                             | - separator
                                             P - page progress percent
                                             B - buffer command
                                             Z - page zoom level
                                       The default is "BP".  These components show nothing if
                                       there is nothing worth showing, like zoom amount 100%.
           statusbar_font              Set the status bar font.  E.g.  statusbar_font = monospace
                                       normal 9.
           tab_style                   Set the tab style to either normal - the default gtk
                                       notebook tabs, or compact for an alternative.  You can
                                       switch the tab style with the tabnextstyle command.
           tabbar_font                 Set the compact tab bar font.  E.g.  tabbar_font =
                                       monospace normal 9.
           url_regex                   This is the regular expression that is used to match what
                                       constitutes a valid URL when using guess_search.
           user_agent                  Set to override the default xxxterm user-agent string. May
                                       be specified several times for switching between user-
                                       agents.
           userstyle_global            When enabled new tabs will automatically be displayed in
                                       low contrast mode.
           window_height               Set the default height of the browser window.
           window_width                Set the default width of the browser window.
           window_maximize             Maximize the browser window at startup.
           work_dir                    Set the work directory where all xxxterm scratch files are
                                       stored.  Default is ~/.xxxterm.
           xterm_workaround            When enabled xxxterm will look additionally at CUT_BUFFER0
                                       if PRIMARY clipboard is empty.  Additionally when the
                                       PRIMARY clipboard is cleared it will copy CUT_BUFFER0 into
                                       the PRIMARY clipboard.  Default is 0.

HISTORY
