You sort off have to hold and swipe, amybe not so easy with a keyboard version.The keypad has a mouse control panel but this doesn't appear to have any scrolling effect either. I can select the menu entries for category but not scroll the list.
more than likely...i would suggest the A2lite if you dont need any mic/voice control as the A3 has a nasty habit of turning off after a few seconds ( apparently to save battery life, but my A2 lite lasts ages !)maybe an A2 or A3 remote would be more effective?
