KEYBOARD(6)                      Games Manual                      KEYBOARD(6)



NAME
       keyboard - how to type characters

DESCRIPTION
       Keyboards are idiosyncratic.  It should be obvious how to type ordinary
       ASCII characters, backspace, tab, escape, and newline.  In Plan 9,  the
       key  labeled  Return or Enter generates a newline (0x0A); if there is a
       key labeled Line Feed, it generates a carriage return  (0x0D);  Plan  9
       eschews  CRLFs.   All control characters are typed in the usual way; in
       particular, control-J is a line feed and control-M a  carriage  return.
       On the PC and some other machines, the key labeled Caps Lock acts as an
       additional control key.

       The delete character (0x7F) may be generated by a  different  key,  one
       near  the  extreme  upper right of the keyboard.  On the Next it is the
       key labeled (not the asterisk above the 8).  On the SLC  and  Sparcsta-
       tion  2,  delete  is  labeled Num Lock (the key above Backspace labeled
       Delete functions as an additional backspace key).  On  the  other  key-
       boards, the key labeled Del or Delete generates the delete character.

       The  view  character (0x80), used by 8(1) and sam(1), causes windows to
       scroll forward.  It is generally somewhere near the lower right of  the
       main  key  area.   The scroll character is generated by the VIEW key on
       the Gnot, the Alt Graph key on the SLC, and any of the three arrow keys
       , , and on the other terminals.

       Characters  in  Plan  9 are runes (see utf(6)).  Any 16-bit rune can be
       typed using a compose key followed by several other keys.  The  compose
       key  is  also  generally near the lower right of the main key area: the
       NUM PAD key on the Gnot, the Alternate key on the Next, the Compose key
       on the SLC, the Option key on the Magnum, and either Alt key on the PC.
       After typing the compose key, type a capital and exactly four hexadeci-
       mal characters (digits and to to type a single rune with the value rep-
       resented by the typed number.  There are shorthands  for  many  charac-
       ters,  comprising the compose key followed by a two- or three-character
       sequence.  There are several rules guiding the design of the sequences,
       as illustrated by the following examples.  The full list is too long to
       repeat here, but is contained in the file  in  a  format  suitable  for
       grep(1) or look(1).

              A  repeated  symbol  gives  a  variant  of that symbol, e.g., ??
              yields .

              ASCII digraphs for mathematical operators give the corresponding
              operator, e.g., <&lt;= yields .

              Two letters give the corresponding ligature, e.g., AE yields .

              Mathematical  and  other  symbols are given by abbreviations for
              their names, e.g., pg yields .

              Chess pieces are given by a w or b followed by a letter for  the
              piece  (k for king, q for queen, r for rook, n for knight, b for
              bishop, or p for pawn), e.g., wk for a white king.

              Greek letters are given by an asterisk followed by a correspond-
              ing latin letter, e.g., *d yields .

              Cyrillic  letters  are  given by an at sign followed by a corre-
              sponding latin letter or letters, e.g., @ya yields .

              Script letters are given by a dollar sign followed by the corre-
              sponding regular letter, e.g., $F yields .

              A digraph of a symbol followed by a letter gives the letter with
              an accent that looks like the symbol, e.g., ,c yields .

              Two digits give the fraction with that numerator  and  denomina-
              tor, e.g., 12 yields .

              The  letter  s followed by a character gives that character as a
              superscript, e.g., s1 yields .

              Sometimes a pair of characters give  a  symbol  related  to  the
              superimposition of the characters, e.g., cO yields .

              A  mnemonic  letter followed by $ gives a currency symbol, e.g.,
              l$ yields .

       Note the difference between  (ss) and  (micron) and the Greek  and .
