NAME

       dumpkeys - dump keyboard translation tables

SYNOPSIS

       dumpkeys  [  -h  --help  -i --short-info -l -s --long-info -n --numeric -f --full-table -1
       --separate-lines -Sshape --shape=shape -t --funcs-only -k  --keys-only  -d  --compose-only
       -ccharset --charset=charset -v --verbose -V --version ]

DESCRIPTION

       dumpkeys  writes,  to  the  standard output, the current contents of the keyboard driver's
       translation tables, in the format specified by keymaps(5).

       Using the various options, the format of the output  can  be  controlled  and  also  other
       information from the kernel and the programs dumpkeys(1) and loadkeys(1) can be obtained.

OPTIONS

       -h --help
              Prints  the  program's  version  number  and a short usage message to the program's
              standard error output and exits.

       -i --short-info
              Prints some characteristics of the kernel's keyboard driver. The items shown are:

              Keycode range supported by the kernel

                     This tells what values can be used after the  keycode  keyword  in  keytable
                     files. See keymaps(5) for more information and the syntax of these files.

              Number of actions bindable to a key

                     This  tells how many different actions a single key can output using various
                     modifier keys. If the value is 16 for example,  you  can  define  up  to  16
                     different  actions  to  a key combined with modifiers. When the value is 16,
                     the kernel probably knows about four modifier keys, which you can  press  in
                     different combinations with the key to access all the bound actions.

              Ranges of action codes supported by the kernel

                     This  item  contains  a  list of action code ranges in hexadecimal notation.
                     These are the values that can be used in  the  right  hand  side  of  a  key
                     definition, ie. the vv's in a line

                            keycode xx = vv vv vv vv

                     (see  keymaps(5)  for  more  information  about the format of key definition
                     lines).  dumpkeys(1) and loadkeys(1) support a symbolic notation,  which  is
                     preferable  to  the numeric one, as the action codes may vary from kernel to
                     kernel while the symbolic names usually remain the same. However,  the  list
                     of  action  code  ranges  can  be  used to determine, if the kernel actually
                     supports all the symbols loadkeys(1) knows, or are there maybe some  actions
                     supported  by  the  kernel  that  have  no symbolic name in your loadkeys(1)
                     program. To see this, you compare the range  list  with  the  action  symbol
                     list, see option --long-info below.

              Number of function keys supported by kernel

                     This  tells the number of action codes that can be used to output strings of
                     characters. These action  codes  are  traditionally  bound  to  the  various
                     function  and  editing keys of the keyboard and are defined to send standard
                     escape sequences. However, you can redefine these  to  send  common  command
                     lines,  email  addresses  or whatever you like.  Especially if the number of
                     this item is greater than the number of function and editing  keys  in  your
                     keyboard, you may have some "spare" action codes that you can bind to AltGr-
                     letter  combinations,  for  example,  to  send  some  useful  strings.   See
                     loadkeys(1) for more details.

              Function strings

                     You can see you current function key definitions with the command

                            dumpkeys --funcs-only

       -l -s --long-info
              This  option  instructs dumpkeys to print a long information listing. The output is
              the same as with  the  --short-info  appended  with  the  list  of  action  symbols
              supported by loadkeys(1) and dumpkeys(1), along with the symbols' numeric values.

       -n --numeric
              This  option  causes  dumpkeys  to  by-pass the conversion of action code values to
              symbolic notation and to print the in hexadecimal format instead.

       -f --full-table
              This makes dumpkeys skip all the short-hand heuristics (see keymaps(5)) and  output
              the  key  bindings  in  the  canonical  form.  First  a keymaps line describing the
              currently defined modifier combinations is printed. Then for each key a row with  a
              column for each modifier combination is printed. For example, if the current keymap
              in use uses seven modifiers, every row will have seven action  code  columns.  This
              format  can  be  useful  for  example  to  programs that post-process the output of
              dumpkeys.

       -Sshape  --shape=shape

       -t --funcs-only
              When  this  option  is  given,  dumpkeys  prints  only  the  function  key   string
              definitions.  Normally  dumpkeys  prints  both  the  key  bindings  and  the string
              definitions.

       -k --keys-only
              When this option is given, dumpkeys prints only the key bindings. Normally dumpkeys
              prints both the key bindings and the string definitions.

       -d --compose-only
              When this option is given, dumpkeys prints only the compose key combinations.  This
              option is available only if your kernel has compose key support.

       -ccharset  --charset=charset
              This instructs dumpkeys  to  interpret  character  code  values  according  to  the
              specified character set. This affects only the translation of character code values
              to symbolic names. Valid values for charset currently are iso-8859-X, Where X is  a
              digit  in  1-9.  If no charset is specified, iso-8859-1 is used as a default.  This
              option produces an output line `charset  "iso-8859-X"',  telling  loadkeys  how  to
              interpret  the  keymap.  (For example, "division" is 0xf7 in iso-8859-1 but 0xba in
              iso-8859-8.)

       -v --verbose

       -V --version
              Prints version number and exits.
