At the risk of inspiring a puppet show...
There's a confirmed bug with the keypad remapping it.
#5 only works with shift depressed or number lock off.
/ and . don't work at all. I mapped (.) to go to start for instance, for some reason it jumps to next item forwards...weird. Justin had a look at it and concluded #5 was kinda tricky, haven't heard back since. I wanted to map (.) to "jump to time window" ala Digital Performer, ended up using Keypad Zero instead.
Have you checked out what the keypad default actions are? I ignored them at first until I couldn't remap all of them, looking in a little deeper their pretty awesome for editing items and moving them, very logical.
If I've misunderstood, please commence video/powerpoint demo
