DUMPKEYS(1)                                                        DUMPKEYS(1)




NAME

       dumpkeys - dump keyboard translation tables


SYNOPSIS

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


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 key-
                     word in keytable files. See keymaps(5) for more  informa-
                     tion 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 hex-
                     adecimal 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) sup-
                     port 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  sym-
                     bols  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 tra-
                     ditionally 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 use-
                     ful 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 list-
              ing.  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.


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


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


       --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.)
