# Outline Menu settings

The settings for customizing Outline Menu are as follows:

RE string | The in-document strings matched by the regular expressions you set here will appear in the drop-down menu. This setting is required in order to search the items to be listed (RE stands for Regular Expression).
IC | If this is selected, case will be ignored during the search. For example, the expression “abc” matches “ABC” or “abc” or “Abc” in your document (IC stands for Ignore Case).
Menu Title Pattern | Here, you can format the titles of the Outline Menu items. Both the “RE string” setting and the setting here determine how the corresponding item is titled in the menu.

The meta characters you can use in Menu Title Pattern are as follows:

(blank) | The whole string matched by your regular expression.
$0, $& | The whole string matched by your regular expression.
$1 ... $9 | The string matched by the first through ninth parenthesized subexpression in your regular expression.
$LN | The line number of a line which contains the first character of the string matched by your regular expression.
- | A separator of the menu (invalid when other letters than “-” are included).

- To show a meta character such as “$0” in the menu, you need to put a backslash (\) in front of it. You won't see that backslash (\) in the menu.
