There is a way to get the current keyboard state and work out what keys are pressed, but its a bit messy and uses the user32.dll. Have a look at the answer to this one.

dependant on which key you want to check do something like this

if(Keyboard.IsKeyDown(Key.LeftCtrl))
    //do something

If Key.LeftCtrl is down, it doesn't mean it is the only key which is down – SiberianGuy Mar 26 '12 at 13:20

Or if you want to want to do something only if that one key is pressed try something like

if(!Keyboard.IsKeyDown(Key.LeftCtrl)) return;

That will throw them out of the function if the key pressed isn't what is required.

But if there were multiple buttons pressed including LeftCtrl e.g. LeftCtrl and RightCtrl it wouldn't throw you out of the function – Ben Mar 26 '12 at 13:30

Maybe you can count the number of KeyDown vs KeyUp? If the counter is 1 and it's the key you want....
