Firefox 2 Tip: Undo closed tab keyboard shortcut

Firefox 2 has a great built-in session manager, which I've become a big fan of. You can easily bring closed tabs back from the dead with this keyboard shortcut: Ctrl-Shift-T

Since Ctrl-T creates a new tab, this makes this keyboard shortcut easy to remember. It works great, espcially when I close the tab next to the one I intended to close.
