Hi steve, we had a thread about this a few weeks ago. You can "teach" the mini keypad commands from the remote (I did this for the VIP air mouse). Here's an extract from my contribution to the thread based on the instructions that came with my mini keypad. It's for setting the on/off switch on the mouse but is supposed to work for other keys as well.
"On/off button on the "flying squirrel" (chinese translation) now works. This is what you do.
Place original supplied remote and air mouse end to end beam side facing.
Press the tv button on the air mouse until the rapidly flashing red light slows down - it is now entering learning mode.
Press the on/off button on the original remote once. This sends the code to the air mouse.
Press the on/off button on the air mouse once to read the code.
Worked first time for me. Suspect it may need some faffing about if it doenst work first time for you."
