How do you get it back?
- First, Tools->Options->Keyboard.
- Show commands containing -> comment
- Click in "Press shortcut keys" and do CTRL+SHIFT+C. It will say "Shortcut currently used by:" write all of them down, if there's more than one (it's a drop-box)
- Under "Shortcuts for selected command", remove each one that isn't CTRL+SHIFT+C
- Now go to each of the commands that you wrote down earlier and remove CTRL+SHIFT+C from each.
Click OK, and you're done.
