Shell script that captures key input? (keylogger)

Question

I want to record all my keystrokes, just to see the frequency of some keys. There is a bunch of keyloggers on google that captures keystrokes, but none that is good and is in the AUR. Isn't it possible to do just with a little shell script? I don't mind if i have to keep the terminal open, and there is no need for any daemon/advanced stuff. Could you record a /dev/something or similar?

Haha, check this out: (cursor=move, z=fire, q=quit)
