Is there any shortcut key (like Ctl C for copy) that we can use for Coloring
a cell.

I actually need to copy certain data from an excel sheet to another system.
Since this is a fairly large data, it becomes difficult for me to remember
the last copied data. Is there any thing I could do to color the cells that
have been copied?
THis way, I will kno that all the cells colored in a particular color are
the ones that have been copied already.
