@emph{text} and @strong{text}
The @emph and @strong commands are for emphasis;
@strong is stronger. In printed output, @emph produces
italics and @strong produces bold.
For example,
@strong{Caution:} @samp{rm * .[^.]*}
removes @emph{all} files in the directory.
produces the following in printed output and HTML:
Caution: `rm * .[^.]*' removes all files in the directory.
and the following in Info:
*Caution:* `rm * .[^.]*' removes _all_
files in the directory.
The @strong command is seldom used except to mark what is, in
effect, a typographical element, such as the word `Caution' in the
preceding example.
In the Info output, @emph surrounds the text with underscores
(`_'), and @strong puts asterisks around the text.
Caution: Do not use@strongwith the word `Note'; Info will mistake the combination for a cross reference. (It's usually redundant, anyway.) Use a phrase such as Please notice or Caution instead, or the optional argument to@quotation—`Note' is allowable there.
