9.2.1 @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. In the Info output, @emph surrounds the text with underscores (‘_’), and @strong puts asterisks around the text.

For example,

@strong{Caution:} @samp{rm *}
removes @emph{all} normal files.

produces the following:

Caution: ‘rm * .[^.]*’ removes all normal files.

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.

Caution: Do not use @strong with the word ‘Note’ followed by a space; Info will mistake the combination for a cross reference. Use a phrase such as Please notice or Caution instead, or the optional argument to @quotation—‘Note’ is allowable there.
