Name G3 as Alpha and enter the formula =G3*2 in G4
Select G4 (or the range of cells to be altered)
Open the Formula tab on Ribbon; go to Defined Names group; click the
launcher (small arrow) on Defined Names too; select Apply

If you type = then click on G3 then type *12 the formula will automatically
be =Alpha*2

best wishes

I remember that Excel versions before 2007 had a feature to automatically
replace cell references in formulas with names. I have not been able to
find
this feature in Excel 2007. Does it still exist, or if not is there
another
way to do it?
