Notepad++, The New Editor King (or, jEdit Dethroned)

I finally gave Notepad++ an honest going over, and it is unquestionably the most flexible tool for editing text the internet has to offer. It:

• handles my keybinding scheme
• is fast(er than jEdit)
• handles large files without choking

You can customize it to a ridiculous degree, and because it uses Scintilla for the editor, schemes should be portable across platforms (Geany, others).

Notepad++'s only real deficiency is its lack of full regex support.
