Wahoo, I found Notepad2. It contains the only two features I really use ALL the time in a text editor: syntax highlighting and UNIX (grep) style regular expressions search and replace.
For those who don’t know about regular expressions search and replace, it allows you to do wacky stuff like swap words, change case, and to pinpoint replacements on a source file, using bits and pieces of what you were “finding” in the “replacement”. Just don’t tell anyone you know how to use it, as it really opens up your ability to process huge input files with ease to do, well, anything.
