<para>When regular expressions are enabled, you can select part of the searched text by enclosing it

within parenthesis. Placeholders allow you to insert such text in the replacement string, similar to

how backreferences are used in sed. When enabled, any occurrence of <keycap>\N</keycap> (where
|
|
|
|
|
<keycap>N</keycap> is an integer number, e.g. \1, \2, ...) will be replaced
|

with the corresponding string capture (parenthesized substring)

from the search pattern. A button for listing all available string captures

will also be enabled. You can click on any of the available string captures
