One thing I've found inconvenient on the Mini 311 is the lack of separate Page Up and Page Down keys. For reading and surfing, having to hold down the fn + arrow key to page up/page down is annoying. So I finally decided to remap some keys using SharpKeys.
I remapped the right Shift key as PgDn and Right Ctrl to PgUp. Now I have the arrow keys, page up and page down all conveniently clustered together on one hand.
Personally, I find losing the extra Shift and Control keys aren't a big deal on a smaller keyboard. There are other keys that could be remapped, but those two make the biggest difference for me. :idea:
Hope it helps!
