Another cross-platform editor, Bluefish is available for Windows, Linux (various distros) and Mac. Its developers pride themselves on its lightweight design; the program is speedy and can handle dozens (or even hundreds, if you believe the documentation) of files simultaneously.
Bluefish gives web developers scope for remote editing with Bluefish, and there’s support for lots of programming languages (including syntax highlighting and checking).
Bluefish won’t be to everyone's liking, largely due to the button-strewn interface – but if you can give the UI a chance, you’ll find it’s a superb text editor.
