Selection screwed up, makes a huge box

I must have hit a wrong key, but whenever I click with the normal mouse button, it makes this GIGANTIC selection box. Worse, I don’t even think it can select anything. I hope someone knows how to fix this cause this pretty much broke Flash and even restarting the app doesn’t help.

Actually, it seems like I broke every single tool, more or less. Mostly it just seems like I’m pressing shift while holding them (line tool draws straight, circle tool makes perfect circle, etc), even though shift isn’t being pressed (I’m not typing in caps)

(Picture:This is what happens when I click. Poorly drawn mouse in there so cause it doesn’t copy with the screen shot)
