In my powerpivot, I have something like Product Group in Row Label.
The different values in Product Group were (and they are still in the power pivot table) Desktop, Notebook, etc.
Now, I clicked on the cell containing Desktop, renaming it to DT (by just typing DT in that cell). Worked great! The problem is now I want to get it back to it's original name "Desktop" and have no idea how to do it. Have searched every imaginable place
on the net, and no luck.
See Image below. The cell showing DT was originally Desktop, before I typed in DT.

Please help.
