Kon is a very fast language sensitive (keywords and html tags in color) text editor. Kon and PMView are the two tools with which I create my Web pages. Occasionally I'll use Embelish to do some retouching on an image because PMView doesn't do pixel editing, just overall image manipulation.

I also use Kon as my programming editor since you can teach it to highlight any language, and it's very good at handling as many source code modules as you want to have open.
