Useful Keypresses in browsers

What’s the best keypresses for browsers?

I’m keen on the following:

  • Alt-D Go to Address Bar
  • Ctrl-Enter Add the www. and .com to your word in the address bar
  • F11 – Ok, it takes you to full-screen.  Not very handy.  But!  Tapping F11 twice makes a non-resizable popup window resizable (IE only).

Any other good ones?  I’d be keen to know the keypress to bring up the IE Dev Toolbar.
