Fonts and Special Characters
and the typesetter allow four different fonts at any one time.
Normally three fonts (Times roman, italic and bold) and one collection of special characters
abcdefghijklmnopqrstuvwxyz 0123456789
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz 0123456789
ABCDEFGHIJKLMNOPQRSTUVWXYZ
abcdefghijklmnopqrstuvwxyz 0123456789

can be followed by a count to
indicate that more than one line is to be italicized.
Fonts can also be changed within a line or word
\efBbold\efIface\efR text
If you want to do this so the previous font, whatever it was,
is left undisturbed, insert extra
\efBbold\efP\efIface\efP\efR text\efP
Because only the immediately previous font is remembered,
you have to restore the previous font after each change
when used without an argument.
There are other fonts available besides the standard set,
although you can still use only four at any given time.
what fonts are physically mounted on the typesetter:
says that the Helvetica font is mounted on position 3.
(The complete list of font sizes and styles depends on
your typesetter or laser printer.)
commands should appear at the beginning of your document
if you do not use the standard fonts.
It is possible to make a document relatively independent
of the actual fonts used to print it
by using font numbers instead of names;
mean `whatever font is mounted at position 3',
and thus work for any setting.
Normal settings are roman font on 1, italic on 2,
There is also a way to get `synthetic' bold fonts
by overstriking letters with a slight offset.
Special characters have four-character names beginning with

greek letters are all of the form

reminiscent of the greek.

That line is unscrambled as follows:
A complete list of these special names occurs in Appendix A.
the same effect can be achieved with the input
SIGMA ( alpha times beta ) \-> inf
which is less concise, but clearer to the uninitiated.

that is, to translate \(mi into \(em.
Some characters are automatically translated into others:
grave \(ga and acute \(aa accents (apostrophes) become open and close single quotes
the combination of ``...'' is generally preferable to the double quotes "...".
Similarly a typed minus sign becomes a hyphen -.
To print an explicit \- sign, use
