You can also use "re-search".

+define Package/mg/description
+ Mg is intended to be a small, fast, and portable editor for people who
+ can't (or don't want to) run emacs for one reason or another, or are not
+ familiar with the vi editor. It is compatible with emacs because there
+ shouldn't be any reason to learn more editor types than emacs or vi.
