A couple of times today I managed to inadvertently ~ mindlessly quit Finder — thereby making all my Desktop folders disappear — via a combination of keystrokes which I can't recapitulate. And once that happens, I've had to restart or re-login to regain the Finder window.
Query: Is there any other means by which to relaunch Finder without having to restart or re-login, preferably via a keyboard shortcut?
Running Mac OS X Lion 10.7.5
