In Texinfo, code is often illustrated in examples that are delimited
@end example, or by
@end lisp. In such examples, you can indicate the results of
evaluation or an expansion using ‘⇒’ or
‘→’. Likewise, there are commands to insert glyphs to
indicate printed output, error messages, equivalence of expressions,
the location of point in an editor, and GUI operation sequences.
The glyph-insertion commands do not need to be used within an example, but most often they are. All glyph-insertion commands are followed by empty braces.
