       dumpkeys - dump keyboard translation tables


       dumpkeys  [  -hilfn1  -Sshape -ccharset --help --short-info --long-info
       --numeric  --full-table  --separate-lines  --shape=shape   --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

       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  keymap  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

              Function strings:

                     You can see you current function key definitions with the


       -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

       -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.

       -1 --separate-lines
              This forces dumpkeys to write one  line  per  (modifier,keycode)
              pair.  It prefixes the word plain for plain keycodes.

       -S --shape=shape
              Tells dumpkeys to use the specified table shape.  Allowed shapes
              are 0: default  shape  (same  as  no  -S);  1:  same  as  option
              --full-table; 2: same as option --separate-lines; 3: display one
              line per keycode (as in shape 1),
               until  first   hole   is   met,   then   use   one   line   per
              (modifier,keycode) pair (as in shape 2).

              When this option is given, dumpkeys prints only the function key
              string  definitions.  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 specified character set. This affects only  the
              translation  of  character  code values to symbolic names. Valid
              values for charset are  listed  by  the  --help  option.  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).
