I just switched to mac from PC and lovin it

However I use excel intensively for work and have been having problems locating funtion keys that work in PC and dont in Mac.

Particularly, F2 key in PC Excel reveals the cells that make up the formula in a particular cell with color coding. These color coded cells can then be dragged etc.

Other the auditing function I have not been able to find a funtion key in excel for mac that does this very important funtion for me.
