I'm using Linux Mint, and I'm having trouble with the Shift key. I'm not sure why, but when I press Space while I have it held down, it does nothing (I'd like it to type a space). Similarly, if I press Space when I have Caps Lock on, it does nothing.
Why is this? Is there some kind of computer shortcut I haven't found that is blocking Shift+Space (and Caps Lock space for whatever reason)?
