How do I recalculate in Excel for Mac? This is driving me a little bit crazy. In my old PC days I used to press either F5 or F9 (I can't remember) to have Excel recalculate.

What is the Mac equivalent?

PS: Perhaps this is not the place to ask. If so, please redirect me. :)
To recalc in Mac:

Command + =

You can try also changing Excel preferences:
Command  ,
Calculation
"Manually" radio button
