# Is is possible to use regular expressions in the search and replace diaglog?

I find myself wanting to be able to do regular expression search and replaces in the Mathematica gui over and over again. Using a regex capable editor (such as vim), I could do something like:

 :,$s/ *+ *s\>//cg  for a prompted search and replace of '+ s', ' +s', '+s', ..., but not '+ sa' (say). Is there any thing that offers similar capability in the Mathematica GUI? • The Find window (Cmd/Ctrl+F) is a notebook, you might get something by exploring the functionality there: Get[FileNameJoin[{$InstallationDirectory,"SystemFiles","FrontEnd","SystemResources","Find.nb"}]] – Martin John Hadley Sep 29 '13 at 1:10
