My Left-Command key keeps bringing up the Mission Control.
I've gone through all the steps in Mac tip: How to restore your keyboard to its default settings to restore all keyboard mappings and shortcuts back to their defaults, but it hasn't fixed the problem.
In TextEditor, I type some text, highlight it, cut it to the clipboard by selecting "Cut <Command>C" from the menu.
If I select "Paste <Command>V" from the menu, the clipboard contents pastes successfully.
But if I try to paste the clipboard contents using the keyboard, by typing <Command>V, nothing pastes, and instead I see a listing of my work spaces appear across the top of the screen, with a '+' at the right.
Any ideas as to what I need to do to get the Command key to work properly?
Mission Control is supposed to be popping up when I press <Ctrl><Up-Arrow>, and that's not working, either.
Oddly enough, my Right-Command key works. That still leaves me with a real problem, because I need to VNC into this machine, and every VNC client I've tried only doesn't distinguish between left and right, they only send LeftC-Command.
