If you haven’t tried it, gleeBox is an amazing extension. I have it installed in my Firefox and Chrome setups, and I’m more than thrilled that it’s finally available for Safari. It lets you do a lot of crazy (and useful) things with keyboard commands on any website. There’s a great writeup over at PimpMySafari.com, so I won’t go into depth on the wonderful parts. I’ll concentrate on the one thing that bugs me about gleeBox: the highlight colors on found and selected elements. They are, in my opinion, a little obnoxious.
