Affects: gedit (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
When you press CTRL-F to find something in gedit, the last search terms
should be pre-selected so that you can start typing a new search over
the old one.

Currently, to make a new search, you have to press CTRL-F, then delete
the old terms, and type the new ones.
