Hya!
Yes, all keys are mapped.
Repag and AVpag are PageUP and PageDown keys.
If I should explain the problem further....I could say that when I move from fwd view to...let's say...left view...it works fine as a snap change...but when I unriliese the j/s view botton...it use instant view to get back to fwd view.
And yes, Arrow UP, DD keys are locked...but....when you press them.....you can see as the view tries to change..but it only moves for a quarter of inch and goes back...turning into a tiny vibration effect.
