       dumpkeys - dump keyboard translation tables

       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 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

              Function strings

                     You can see you current function key definitions with the

                            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

       -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

       -v --verbose

       -V --version
              Prints version number and exits.
