Here I go again, professing my love for keyboard shortcuts. I have shortcuts and hotkeys for just about everything I do on a daily basis. I'm running out of intuitive combinations, actually, but my muscle memory seems to have room for a few more. There's one shortcut, though, that I think every Safari user -- keyboard-obsessed or not -- really should know about.
If you have a Mac, and forgive my bold assumption that you do, you already have your own copy of Safari's lesser-known keyboard shortcuts on your drive. It's buried inside of the Safari application bundle, but you can reach it directly from a Web browser (Safari or not) at file:///Applications/Safari.app/Contents/Resources/Shortcut
