DESCRIPTION

Each line in the file can describe a key or an accent. A ‘#’ character begins a comment, which extends to the end of the line.

The description of a key begins with the scancode for that key. Then the effect of the key under combinations of shift, control and alt are listed in the following order: no modifier, shift, control, control and shift, alt, alt and shift, alt and control, alt and control and shift. The action of the key under each modifier can be:

'symbol'

The symbol the key should produce, in single quotes.

decnum

The ASCII value to produce as a decimal number (see ascii(7)). For example, 32 for space.

0xhexnum

The ASCII value to produce as a hexadecimal number. For example, 0x20 for space.

ctrlname

One of the standard names for the ASCII control characters: nul, soh, stx, etx, eot, enq, ack, bel, bs, ht, nl, vt, np, cr, so, si, dle, dc1, dc2, dc3, dc4, nak, syn, etb, can, em, sub, esc, fs, gs, rs, ns, us, sp, del.

accentname

By giving one of the accent names, the next key pressed will produce an accented character in accordance with that accent. See the description of accents below. The accent names are: dgra, dacu, dcir, dtil, dmac, dbre, ddot, duml, ddia, dsla, drin, dced, dapo, ddac, dogo, dcar.

Finally, to complete the description of a key, a flag which describes the effect of caps lock and num lock on that key is given. The flag can be ‘C’ to indicate that caps lock affects the key, ‘N’ to indicate that num lock affects the key, ‘B’ to indicate that both caps lock and num lock affects the key, or ‘O’ to indicate that neither affects the key.

An accent key works by modifying the behavior of the next key pressed. The description of an accent begins with one of the accent names given above. This is followed by the symbol for the accent, given in single quotes or as a decimal or hexadecimal ASCII value. This symbol will be produced if the accent key is pressed and then the space key is pressed.

The description of the accent key continues with a list showing how it modifies various symbols, by giving pairs made up of the normal symbol and the modified symbol enclosed in parentheses. Both symbols in a pair can be given in either single quotes or as decimal or hexadecimal ASCII values.

For example, consider the following extract from a kbdmap:

  041   dgra   172    nop    nop    '|'    '|'    nop    nop     O
  dgra  '`'  ( 'a' 224 ) ( 'A' 192 ) ( 'e' 232 ) ( 'E' 200 )
             ( 'i' 236 ) ( 'I' 204 ) ( 'o' 242 ) ( 'O' 210 )
             ( 'u' 249 ) ( 'U' 217 )
