In Konqueror, the key presses for up down and enter arrows are not registered (all key presses come back with a keyCode of 0). Is this because Konqueror only registers keyCodes on text inputs (and the key presses are on the divs of the drop-down box)? Does anyone know of any other methods that also work with Konqueror? (Tested on Konqueror 3.5.4).
