4 83bab5af 2005-07-18 devnull .SH DESCRIPTION
5 83bab5af 2005-07-18 devnull Keyboards are idiosyncratic.
6 83bab5af 2005-07-18 devnull It should be obvious how to type ordinary
8 83bab5af 2005-07-18 devnull characters,
9 83bab5af 2005-07-18 devnull backspace, tab, escape, and newline.
10 83bab5af 2005-07-18 devnull In Plan 9, the key labeled
11 83bab5af 2005-07-18 devnull .B Return
14 83bab5af 2005-07-18 devnull generates a newline
15 83bab5af 2005-07-18 devnull .RB ( 0x0A );
16 83bab5af 2005-07-18 devnull if there is a key labeled
18 83bab5af 2005-07-18 devnull .BR Feed ,
19 83bab5af 2005-07-18 devnull it generates a carriage return
20 83bab5af 2005-07-18 devnull .RB ( 0x0D );
21 83bab5af 2005-07-18 devnull Plan 9 eschews CRLFs.
22 83bab5af 2005-07-18 devnull All control characters are typed in the usual way;
23 83bab5af 2005-07-18 devnull in particular, control-J is a line feed and control-M a carriage return.
24 83bab5af 2005-07-18 devnull .\" On the PC and some other machines, the key labeled
25 83bab5af 2005-07-18 devnull .\" .B Caps
26 83bab5af 2005-07-18 devnull .\" .B Lock
27 83bab5af 2005-07-18 devnull .\" acts as an additional control key.
29 83bab5af 2005-07-18 devnull .\" The delete character
30 83bab5af 2005-07-18 devnull .\" .RB ( 0x7F )
31 83bab5af 2005-07-18 devnull .\" may be generated by a different key,
32 83bab5af 2005-07-18 devnull .\" one near the extreme upper right of the keyboard.
33 83bab5af 2005-07-18 devnull .\" On the Next, it is the key labeled
35 83bab5af 2005-07-18 devnull .\" (not the asterisk above the 8).
36 83bab5af 2005-07-18 devnull .\" On the SLC and Sparcstation 2, delete is labeled
37 83bab5af 2005-07-18 devnull .\" .B Num
38 83bab5af 2005-07-18 devnull .\" .B Lock
39 83bab5af 2005-07-18 devnull .\" (the key above
40 83bab5af 2005-07-18 devnull .\" .B Backspace

42 83bab5af 2005-07-18 devnull .\" .B Delete
43 83bab5af 2005-07-18 devnull .\" functions as an additional backspace key).
44 83bab5af 2005-07-18 devnull .\" On the other keyboards, the key labeled
45 83bab5af 2005-07-18 devnull .\" .B Del
47 83bab5af 2005-07-18 devnull .\" .B Delete
48 83bab5af 2005-07-18 devnull .\" generates the delete character.
50 83bab5af 2005-07-18 devnull The down arrow,
52 83bab5af 2005-07-18 devnull .IR 9term (1),

62 83bab5af 2005-07-18 devnull other keys.
63 83bab5af 2005-07-18 devnull The compose key is also generally near the lower right of the main key area:

70 83bab5af 2005-07-18 devnull key on the SLC, the
71 83bab5af 2005-07-18 devnull .B Option
72 83bab5af 2005-07-18 devnull key on the Magnum, and either
74 83bab5af 2005-07-18 devnull key on the PC.
75 83bab5af 2005-07-18 devnull After typing the compose key, type a capital
77 83bab5af 2005-07-18 devnull and exactly four hexadecimal characters (digits and
81 83bab5af 2005-07-18 devnull to type a single rune with the value represented by
82 83bab5af 2005-07-18 devnull the typed number.
83 83bab5af 2005-07-18 devnull There are shorthands for many characters, comprising
84 83bab5af 2005-07-18 devnull the compose key followed by a two- or three-character sequence.
85 83bab5af 2005-07-18 devnull There are several rules guiding the design of the sequences, as
86 83bab5af 2005-07-18 devnull illustrated by the following examples.
87 83bab5af 2005-07-18 devnull The full list is too long to repeat here, but is contained in the file
88 83bab5af 2005-07-18 devnull .L \*9/lib/keyboard

92 83bab5af 2005-07-18 devnull .IR look (1).
94 83bab5af 2005-07-18 devnull A repeated symbol gives a variant of that symbol, e.g.,
96 83bab5af 2005-07-18 devnull yields ¿\|.
98 83bab5af 2005-07-18 devnull .SM ASCII
99 83bab5af 2005-07-18 devnull digraphs for mathematical operators give the corresponding operator, e.g.,
101 83bab5af 2005-07-18 devnull yields ≤.
103 83bab5af 2005-07-18 devnull Two letters give the corresponding ligature, e.g.,
105 83bab5af 2005-07-18 devnull yields Æ.
107 83bab5af 2005-07-18 devnull Mathematical and other symbols are given by abbreviations for their names, e.g.,
109 83bab5af 2005-07-18 devnull yields ¶.
111 83bab5af 2005-07-18 devnull Chess pieces are given by a
