45 Fonts and Special Characters
48 and the typesetter allow four different fonts at any one time.
49 Normally three fonts (Times roman, italic and bold) and one collection of special characters
54 abcdefghijklmnopqrstuvwxyz 0123456789
55 ABCDEFGHIJKLMNOPQRSTUVWXYZ
57 abcdefghijklmnopqrstuvwxyz 0123456789
58 ABCDEFGHIJKLMNOPQRSTUVWXYZ
60 abcdefghijklmnopqrstuvwxyz 0123456789
61 ABCDEFGHIJKLMNOPQRSTUVWXYZ
65 greek, mathematical symbols and miscellany
66 of the special font are
70 prints in roman unless told otherwise.
71 To switch into bold, use
82 To return to roman, use
84 to return to the previous font,
90 The `underline' command
94 causes the next input line to print in italics.
96 can be followed by a count to
97 indicate that more than one line is to be italicized.
99 Fonts can also be changed within a line or word
100 with the in-line command
103 \fBbold\fIface\fR text
107 \efBbold\efIface\efR text
109 If you want to do this so the previous font, whatever it was,
110 is left undisturbed, insert extra
114 \efBbold\efP\efIface\efP\efR text\efP
116 Because only the immediately previous font is remembered,
117 you have to restore the previous font after each change
123 when used without an argument.
125 There are other fonts available besides the standard set,
126 although you can still use only four at any given time.
131 what fonts are physically mounted on the typesetter:
135 says that the Helvetica font is mounted on position 3.
136 (The complete list of font sizes and styles depends on
137 your typesetter or laser printer.)
140 commands should appear at the beginning of your document
141 if you do not use the standard fonts.
143 It is possible to make a document relatively independent
144 of the actual fonts used to print it
145 by using font numbers instead of names;
150 mean `whatever font is mounted at position 3',
151 and thus work for any setting.
152 Normal settings are roman font on 1, italic on 2,
156 There is also a way to get `synthetic' bold fonts
157 by overstriking letters with a slight offset.
163 Special characters have four-character names beginning with
165 and they may be inserted anywhere.
172 \e(14 + \e(12 = \e(34
175 greek letters are all of the form
179 is an upper or lower case roman letter
180 reminiscent of the greek.
184 \(*S(\(*a\(mu\(*b) \(-> \(if
190 \e(*S(\e(*a\e(mu\e(*b) \e(\(mi> \e(if
192 That line is unscrambled as follows:
204 A complete list of these special names occurs in Appendix A.
209 the same effect can be achieved with the input
211 SIGMA ( alpha times beta ) \-> inf
213 which is less concise, but clearer to the uninitiated.
217 four-character name is a single character
226 is perfectly clear, meaning
230 that is, to translate \(mi into \(em.
232 Some characters are automatically translated into others:
233 grave \(ga and acute \(aa accents (apostrophes) become open and close single quotes
235 the combination of ``...'' is generally preferable to the double quotes "...".
236 Similarly a typed minus sign becomes a hyphen -.
237 To print an explicit \- sign, use
239 To get a backslash printed, use
