The control-key on my MacBook Pro (OS X 10.8.4) has started behaving strangely. When I press it it acts in the same way as F10, bringing up Application Windows. This is a nuisance, as it affects key combinations that include the control-key.
I have no idea how this started, but I'd like to be able to stop it!

Open Mission Control in System Preferences. You should check if Left Control Key is being used to call Mission Control. Try to remove it from selections.
