Use 'keyup' event to detect the active state

[autarc]

At least on Linux there was an issue with detecting the active state by relying on the keyboard repeat rate. The highlighted links were just temporary visible for the first 500ms and then disappeared although the modifier key kept being pressed. Works on my system so far - do you still have troubles on yours using the event listeners ?
