I've just got a new MBP, and an SORELY missing the 'enter' key to the right of the space bar. I work with After Effects and would use it all the time. Having to modify the 'return' key with 'fn' is pretty annoying. Also missing - the numeric modifiers on the letter keys, particularly '0' on 'm'. I can find no shortcut for RAM previewing now.
Is there any way to re-map the right 'option' key to 'enter', and 'fn' 'm' to what would be zero on the extended keyboard?
