Q. I know I can add a column of numbers by writing a formula such as =sum(A1+A12 , or by clicking on AutoSum ( ). But is there a way to do this using a faster keyboard approach?
A. Yes, and the keyboard approach is much, much quicker. Just click on a cell at the bottom of any column you want to add (it can even be many cells below the last number), hold down the Alt key, type in = and then press Enter.
