DUMPKEYS(1)                          General Commands Manual                          DUMPKEYS(1)

       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 dif‐
                     ferent 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 dif‐
                     ferent 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 defi‐
                     nition, 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  sup‐
                     ports  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)  pro‐
                     gram.  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 func‐
                     tion 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 load‐
                     keys(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 sup‐
              ported 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 sym‐
              bolic 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  cur‐
              rently  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  dump‐

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

              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  speci‐
              fied  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

       /usr/share/keymaps  recommended directory for keytable files
