jEdit. I'm surprised nobody seems to be using it considering how powerful it is. I have tried many editors over the years and SublimeText is the first one that comes close to it; but jEdit still has much better search functionality, especially in 'hypersearch' mode.
Totally love jEdit, especially the search functionality. I've been using it for more than 7 years now, though development of jEdit and plugins have slowed in recent years. I've tried using Sublime and Notepad++ but both of them don't feel right.
If jEdit were written in something other than Java, then it truly would have been an emacs successor. Unfortunately it's Java background is simultaneously both it's weakness and it's strength.
