9.2.3 Fonts for Printing, Not Info

Texinfo provides a number of font commands that specify font changes in the printed manual and (where possible) in the HTML output, but have no effect in the Info file. All the commands apply to an argument that follows, surrounded by braces.

@b

selects bold face;

@i

selects an italic font;

@r

selects a roman font, which is the usual font in which text is printed. It may or may not be seriffed.

@sansserif

selects a sans serif font;

@slanted

selects a slanted font;

@t

selects the fixed-width, typewriter-style font used by @code;

(The commands with longer names were invented much later than the others, when it did not seem desirable to use very short names for such an infrequently needed feature.)

Only the @r command has much use: in example-like environments, you can use the @r command to write comments in the standard roman font instead of the fixed-width font. This looks better in printed output, and produces a <lineannotation> tag in Docbook output.

For example,

     @lisp
     (+ 2 2)    ; @r{Add two plus two.}
     @end lisp

produces

     (+ 2 2)    ; Add two plus two.

In general, you should avoid using the other font commands. Some of them are only useful when documenting functionality with specific font effects, such as in \TeX\ and related packages.
