Considering how many linux users use Midnight Commander, I'm surprised to find that I'm the first to mention that I prefer to use "mcedit"...just hit the old F4 button. Reasons are....nice color syntaxing and when you are done editing, a quick press of the enter key runs the script. Plus the F3 key gives a built-in hex-editor for close examination of output. It also has "good enough" cut'n'paste abilities from console or xterm.
Another free Windows editor that includes highlighting and many other features is Crimson Editor. If you're used EditPlus, Crimson is extremely similar.
That said, I'm using gvim on a sun and considering moving on to emacs soon.
