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 rio(1), acme(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 the arrow key â
       on the other terminals.  As a convenience for sloppy typists, some pro‐
       grams interpret â and â keys, which lie on either side of  â,  as  view
       keys as well.  The arrow key â scrolls backward.

       Characters in Plan 9 are runes (see utf(6)).  Any rune can be typed us‐
       ing 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 lower case and  up  to  six  hexadecimal
       characters  (digits  and to followed by a semicolon (if the sequence is
       less than six digits long) to type a single rune with the value  repre‐
       sented  by the typed number.  There are shorthands for many characters,
       comprising the compose key followed by a two-  or  three-character  se‐
       quence.   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., <= yields â¤.

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

              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 Î'.

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

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

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

              Two  digits  give the fraction with that numerator and denomina‐
              tor, e.g., 12 yields ½.

              The letter s followed by a character gives that character  as  a
              superscript,  e.g.,  s1  yields  â±.  These characters are taken
              from the Unicode block 0x2070; the 1, 2, and 3  superscripts  in
              the  Latin-1 block are available by using a capital S instead of
              s.

              Sometimes a pair of characters give a symbol related to the  su‐
              perimposition of the characters, e.g., cO yields ©.

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

       Note the difference between à (ss) and µ (micron) and the Greek β and
       μ.
