       dumpkeys - dump keyboard translation tables


       dumpkeys  [  -hilfn  -ccharset  --help  --short-info  --long-info  --numeric  --full-table
       --funcs-only --keys-only --compose-only --charset=charset ]


       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.


       -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 --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

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

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

              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
