       keyboard - how to type characters

       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  par-
       ticular,  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 Sparcstation  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 81/2(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 <-, v, 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 hexadecimal characters (dig-
       its and to to type a single rune with the value represented by the  typed  number.   There
       are  shorthands	for  many  characters,	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 c.

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

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

	      Mathematical and other symbols are given by abbreviations for their names, e.g., pg
	      yields 9|.

	      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  corresponding  latin  letter,
	      e.g., *d yields d.

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

	      Script letters are given by a dollar sign followed  by  the  corresponding  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 c.

	      Two digits give the fraction with that numerator and denominator, e.g.,  12  yields

	      The  letter  s followed by a character gives that character as a superscript, e.g.,
	      s1 yields 1.

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

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

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