Lots of updates coming, but a quick tidbit...
Today I was saying to myself for the 100th time, "Man, I wish I had emacs keybinding in browser text fields!" I wondered how hard it would be to write a Greasemonkey user script to do it, so I started searching to see if anyone beat me to the idea. Turns out, on Linux, it's supported natively (sort-of) by GTK, and if you're on other platforms, it's possible by hacking around with some mozilla XML files.
See:
snarfed.org: emacs keybindings in firefox
MozillaZine: Emacs Keybindings
I still think I might be able to write a Greasemonkey user script that would better do what I want, but for now, this will do.
Oh, and if you don't know what emacs is, sorry for boring you.
