16.4 @deffnx, et al.: Two or More ‘First’ Lines

To create two or more ‘first’ or header lines for a definition, follow the first @deffn line by a line beginning with @deffnx. The @deffnx command works exactly like @deffn except that it does not generate extra vertical white space between it and the preceding line.

For example,

@deffn {Interactive Command} isearch-forward
@deffnx {Interactive Command} isearch-backward
These two search commands are similar except …
@end deffn

produces

Interactive Command: isearch-forward

Interactive Command: isearch-backward

These two search commands are similar except …

Each definition command has an ‘x’ form: @defunx, @defvrx, @deftypefunx, etc.

The ‘x’ forms work similarly to @itemx (see section @itemx: Second and Subsequent Items).
