I just stumbled across this little gem...

If you have pages in your bookmarks bar in Safari, hit Command+1 to open the first one, Command+2 to open the second, etc...

My bookmarks bar is mostly full of folders, but there are a couple of pages, and the Command+# maps to their non-folder order from the left side

Quite cool. Wonder what other goodness is hiding in there... Already have mouse gesturing thanks to Cocoa Gestures. Slick.
