1. Lift the screen on press of shift or control, the traditional
for clearing a screensaver (I think there's a bugzilla for this)
2. If someone is moving the mouse around for a while and hasn't
figured out what those arrows mean, maybe display some text? Or
something that looks like a clickable button?
I agree - the lock screen doesnt provide enough hints to the user as to
how to unlock it.
