-h

Prints the program's version number and a short usage message to the program's standard error output and exits.

-i

Prints some characteristics of the kernel's keyboard driver. The items shown are:Keycode range supported by the kernelThis tells what values can be used after the keycode keyword in keytable files. See keymaps(5) for more information andthe syntax of these files.Number of actions bindable to a keyThis tells how many different actions a single key can output using various modifier keys. If the value is 16 for exam‐ple, you can define up to 16 different actions to a key combined with modifiers. When the value is 16, the kernel prob‐ably knows about four modifier keys, which you can press in different combinations with the key to access all the boundactions.Ranges of action codes supported by the kernelThis item contains a list of action code ranges in hexadecimal notation. These are the values that can be used in theright hand side of a key definition, ie. the vv's in a linekeycode xx = vv vv vv vv(see keymaps(5) for more information about the format of key definition lines). dumpkeys(1) and loadkeys(1) support asymbolic notation, which is preferable to the numeric one, as the action codes may vary from kernel to kernel while thesymbolic names usually remain the same. However, the list of action code ranges can be used to determine, if the kernelactually supports all the symbols loadkeys(1) knows, or are there maybe some actions supported by the kernel that haveno symbolic name in your loadkeys(1) program. To see this, you compare the range list with the action symbol list, seeoption --long-info below.Number of function keys supported by kernelThis tells the number of action codes that can be used to output strings of characters. These action codes are tradi‐tionally bound to the various function and editing keys of the keyboard and are defined to send standard escapesequences. However, you can redefine these to send common command lines, email addresses or whatever you like. Espe‐cially if the number of this item is greater than the number of function and editing keys in your keyboard, you mayhave some "spare" action codes that you can bind to AltGr-letter combinations, for example, to send some usefulstrings. See loadkeys(1) for more details.Function stringsYou can see you current function key definitions with the commanddumpkeys --funcs-only

-l

This option instructs dumpkeys to print a long information listing. The output is the same as with the --short-info appendedwith the list of action symbols supported by loadkeys(1) and dumpkeys(1), along with the symbols' numeric values.

-n

This option causes dumpkeys to by-pass the conversion of action code values to symbolic notation and to print the in hexadeci‐mal format instead.

-f

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 columnfor each modifier combination is printed. For example, if the current keymap in use uses seven modifiers, every row will haveseven action code columns. This format can be useful for example to programs that post-process the output of dumpkeys.

-t

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

-k

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

-d

When this option is given, dumpkeys prints only the compose key combinations. This option is available only if your kernelhas compose key support.

-ccharset

This instructs dumpkeys to interpret character code values according to the specified character set. This affects only thetranslation of character code values to symbolic names. Valid values for charset currently are iso-8859-X, Where X is a digitin 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 iniso-8859-8.)

-V

Prints version number and exits.FILES/usr/share/keymaps recommended directory for keytable files
