Hitch,
I've looked both UltraEdit and NoteTab Pro both in trial versions. They are both pretty close; both have spell checkers, etc. but one definite advantage is the UE has a well defined Perl regex and has both a short list of the syntax and a url reference to a more complete one from
http://www.boost.org/doc/libs/1_33_1....html#synopsis.
This means that I know exactly what syntax will work in UE whereas I'm not clear about this with NTP. For example, the regex express \s+ worked in UE (and Sigil) but not in NTP. What flavor of regex does NTP or Notepad++ use? My major problem with regex is that I never know which of the many flavors I'm working with in a particular program. Then I get frustrated when something that should work according to a web page doesn't work. As a beginner with regex this is a particularly difficult sort of problem.
