NAME

       Gromit-MPX - Presentation helper to make annotations on screen

SYNOPSIS

       gromit-mpx [options]

DESCRIPTION

       Gromit-MPX enables you to make multi-pointer annotations on your screen. It can run in the
       background and be activated on demand to let you draw  over  all  your  currently  running
       applications. The drawing will stay on screen as long as you want, you can continue to use
       your applications while the drawing is visible.
       Gromit-MPX is XInput-Aware, so if you have a  graphic  tablet  you  can  draw  lines  with
       different strength, colour, erase things, etc.
       Since  you  typically  want  to  use  the  program  you are demonstrating and highlighting
       something is a short interruption of you workflow, Gromit-MPX is  activated  by  either  a
       hotkey  or  a  repeated  invocation  of  Gromit-MPX  (the  latter  can  e.g. used by other
       applications or your windowmanager).

KEYBOARD CONTROL

       By default, Gromit-MPX grabs the "F9" key (this can be changed using the "--key"  option),
       making it unavailable to other application. The available shortcuts are:

       F9     toggle painting

       SHIFT-F9
              clear screen

       CTRL-F9
              toggle visibility

       ALT-F9 quit Gromit-MPX

OPTIONS (STARTUP)

       A  short summary of the available commandline arguments for invoking Gromit-MPX, see below
       for the options to control an already running Gromit-MPX process:

       -a, --active
              start Gromit-MPX and immediately activate it.

       -d, --debug
              gives some debug output.

       -k <keysym>, --key <keysym>
              will change the key used to grab the mouse.  <keysym>  can  e.g.  be  "F9",  "F12",
              "Control_R"  or "Print". To determine the keysym for different keys you can use the
              xev(1) command. You can specify "none" to prevent Gromit-MPX from grabbing a key.

       -K <keycode>, --keycode <keycode>
              will change the key used to grab the mouse. Under  rare  circumstances  identifying
              the  key  with the keysym can fail. You can then use the keycode to specify the key
              uniquely. To determine the keycode for  different  keys  you  can  use  the  xev(1)
              command.

       -o, --opacity <value>
              will  set  the initial opacity of the window using a floating point value between 0
              and 1.

       -u <keysym>, --undo-key <keysym>
              will change the key used to undo/redo strokes. <keysym> can e.g.  be  "F9",  "F12",
              "Control_R"  or "Print". To determine the keysym for different keys you can use the
              xev(1) command. You can specify "none" to prevent Gromit-MPX from grabbing a key.

       -U <keycode>, --undo-keycode <keycode>
              will change the key used to undo/redo strokes. Under rare circumstances identifying
              the  key  with the keysym can fail. You can then use the keycode to specify the key
              uniquely. To determine the keycode for  different  keys  you  can  use  the  xev(1)
              command.

OPTIONS (CONTROL)

       A  sort  summary  of  the  available  commandline  arguments to control an already running
       Gromit-MPX process, see above for the options available to start Gromit-MPX.

       -c, --clear
              will clear the screen.

       -q, --quit
              will cause the main Gromit-MPX process to quit.

       -t, --toggle
              will toggle the grabbing of the cursor.

       -v, --visibility
              will toggle the visibility of the window.

       -y, --redo
              will redo the last undone drawing stroke.

       -z, --undo
              will undo the last drawing stroke.

ENVIRONMENT

       GDK_BACKEND
              Set to force use of a particular backend, valid values are x11 or wayland.

       XDG_CONFIG_HOME
              Directory to search for user's custom configuration file, defaults to ~/.config/.

FILES

       gromit-mpx.cfg
              Configuration file which defines pens and maps mouse buttons and modifiers to them.
              Searched for in user's custom configuration file directory and, if not found there,
              in /etc/gromit-mpx/.

BUGS

       When there is no compositing manager such as Compiz, xcompmgr or Mutter  running,  Gromit-
       MPX  falls  back  to  a legacy drawing mode. This may drastically slow down your X-Server,
       especially when you draw very thin lines. It makes heavy use of the shape extension, which
       is  quite expensive if you paint a complex pattern on screen. Especially terminal-programs
       tend to scroll incredibly slow if something is painted over their window.
