search_again

 Repeats the last search_for or search_replace. The search continues using
 the scope and settings as set up by the earlier search_for or
 search_replace.

 If you have moved out of the scope of searching since the original search
 command, this command will prompt to see if you wish to reset the scope of
 the search to the current fold and below.

 If you don't wish to reset the scope then the search will not proceed.
