I love the "Find in Files" functionality in EmEditor, since I let me choose file externsions and what character encoding to use. Now I'd like to askwhether there is a find option that lets me find only in text files.

It is really useful when I want to deal with an unfamilar software. I'd like to find a string(probably a configuration name or its value) in all files within that software's directory, but I cannot figure out what file extensions to find(maybe .ini .cfg .bat .xml or something else), so the best strategy is to find in all text files.
