9 backspace, tab, escape, and newline.
10 In Plan 9, the key labeled
16 if there is a key labeled
19 it generates a carriage return
22 All control characters are typed in the usual way;
23 in particular, control-J is a line feed and control-M a carriage return.
24 .\" On the PC and some other machines, the key labeled
27 .\" acts as an additional control key.
29 .\" The delete character
31 .\" may be generated by a different key,
32 .\" one near the extreme upper right of the keyboard.
33 .\" On the Next, it is the key labeled
35 .\" (not the asterisk above the 8).
36 .\" On the SLC and Sparcstation 2, delete is labeled
43 .\" functions as an additional backspace key).
44 .\" On the other keyboards, the key labeled
48 .\" generates the delete character.

57 The up arrow scrolls backward.
59 Characters in Plan 9 are runes (see
61 Any 16-bit rune can be typed using a compose key followed by several
63 The compose key is also generally near the lower right of the main key area:
72 key on the Magnum, and either
75 After typing the compose key, type a capital
77 and exactly four hexadecimal characters (digits and

83 There are shorthands for many characters, comprising
84 the compose key followed by a two- or three-character sequence.
85 There are several rules guiding the design of the sequences, as
86 illustrated by the following examples.

89 in a format suitable for
94 A repeated symbol gives a variant of that symbol, e.g.,
99 digraphs for mathematical operators give the corresponding operator, e.g.,
103 Two letters give the corresponding ligature, e.g.,
107 Mathematical and other symbols are given by abbreviations for their names, e.g.,
111 Chess pieces are given by a
115 followed by a letter for the piece
132 Greek letters are given by an asterisk followed by a corresponding latin letter,
137 Cyrillic letters are given by an at sign followed by a corresponding latin letter or letters,
142 Script letters are given by a dollar sign followed by the corresponding regular letter,
147 A digraph of a symbol followed by a letter gives the letter with an accent that looks like the symbol, e.g.,
151 Two digits give the fraction with that numerator and denominator, e.g.,
155 The letter s followed by a character gives that character as a superscript, e.g.,
158 These characters are taken from the Unicode block 0x2070; the 1, 2, and 3
159 superscripts in the Latin-1 block are available by using a capital S instead of s.
161 Sometimes a pair of characters give a symbol related to the superimposition of the characters, e.g.,
165 A mnemonic letter followed by $ gives a currency symbol, e.g.,
