keytables(5)

Name

keytables - keyboard table descriptions for loadkeys and dumpkeys

Description

These files are used by loadkeys(1) to modify the translation tables used by the keyboard streams module and generated from those translation tables. See loadkeys(1).

Any line in the file beginning with # is a comment, and is ignored. # is treated specially only at the beginning of a line.

Other lines specify the values to load into the tables for a particular keystation. The format is either:

key number list_of_entries

or

swap number1 with number2

or

key number1 same as number2

or a blank line, which is ignored.

key number list_of_entries

sets the entries for keystation number from the list given. An entry in that list is of the form

tablename code

where tablename is the name of a particular translation table, or all. The translation tables are:

base

entry when no shifts are active

shift

entry when "Shift" key is down

caps

entry when "Caps Lock" is in effect

ctrl

entry when "Control" is down

altg

entry when "Alt Graph" is down

numl

entry when "Num Lock" is in effect

up

entry when a key goes up

All tables other than up refer to the action generated when a key goes down. Entries in the up table are used only for shift keys, since the shift in question goes away when the key goes up, except for keys such as "Caps Lock" or "Num Lock"; the keyboard streams module makes the key look as if it were a latching key.

A table name of all indicates that the entry for all tables should be set to the specified value, with the following exception: for entries with a value other than hole, the entry for the numl table should be set to nonl, and the entry for the up table should be set to nop.

The code specifies the effect of the key in question when the specified shift key is down. A code consists of either:

  • A character, which indicates that the key should generate the given character. The character can either be a single character, a single character preceded by ^ which refers to a "control character" (for instance, ^c is control-C), or a C-style character constant enclosed in single quote characters ('), which can be expressed with C-style escape sequences such as \r for RETURN or \000 for the null character. Note that the single character may be any character in an 8-bit character set, such as ISO 8859/1.

  • A string, consisting of a list of characters enclosed in double quote characters ("). Note that the use of the double quote character means that a code of double quote must be enclosed in single quotes.

  • One of the following expressions:

    shiftkeys+leftshift

    the key is to be the left-hand "Shift" key

    shiftkeys+rightshift

    the key is to be the right-hand "Shift" key

    shiftkeys+leftctrl

    shiftkeys+rightctrl

    the key is to be the right-hand "Control" key

    shiftkeys+alt

    nop

    the key is to do nothing

    error

    this code indicates an internal error; to be used only for keystation 126, and must be used there

    idle

    this code indicates that the keyboard is idle (that is, has no keys down); to be used only for all entries other than the numl and up table entries for keystation 127, and must be used there

    oops

    this key exists, but its action is not defined; it has the same effect as nop

    reset

    this code indicates that the keyboard has just been reset; to be used only for the up table entry for keystation 127, and must be used there.

    swap number1 with number2

    exchanges the entries for keystations number1 and number2.

    key number1 same as number2

    sets the entries for keystation number1 to be the same as those for keystation number2. If the file does not specify entries for keystation number2, the entries currently in the translation table are used; if the file does specify entries for keystation number2, those entries are used.

Examples

Example 1 Example of setting multiple keystations.

The following entry sets keystation 15 to be a “hole” (that is, an entry indicating that there is no keystation 15); sets keystation 30 to do nothing when Alt Graph is down, generate "!" when Shift is down, and generate "1" under all other circumstances; and sets keystation 76 to be the left-hand Control key.

key 15   all hole
key 30   base 1 shift ! caps 1 ctrl 1 altg nop
key 76   all shiftkeys+leftctrl up shiftkeys+leftctrl
Example 2 Exchange DELETE and BACKSPACE keys

The following entry exchanges the Delete and Back Space keys on the Type 4 keyboard:

swap 43 with 66

Keystation 43 is normally the Back Space key, and keystation 66 is normally the Delete key.

Example 3 Disable CAPS LOCK key

The following entry disables the Caps Lock key on the Type 3 and U.S. Type 4 keyboards:

key 119 all nop
Example 4 Standard translation tables for the U.S. Type 4 keyboard

The following specifies the standard translation tables for the U.S. Type 4 keyboard:
