Fill colour
 

Hi,
I have SUM formula in one of the cell.
For Example I have a formula in cell# A1. And the formula is
A52+A54+A84+A95+A96+B101+B105+C96+D201 etc.,

by holding the F2 button in cell#A1 I can see all precedents of this cell. I
wanted to fill the colours in these cells by holidng F2 Button. but its not
allowing me to fill the colours in these cells.
Is there any other way i can fill the colour by holding F2 buttons or any
other shortcuts in Excel 2007
Regards,
Vishu
