Usually when I have a simple formula in Excel
(A1+A2) if I click in cell containing the formula a blue and a pink box will highlight cells
A2 and I can move the reference point around if I like.
Recently someone tried to use my laptop and hit a bunch of shortcuts and one has disabled this feature.
Now when I click on a cell the reference points are no longer highlighted. The formula cell still displays the product of the calculation.
Any ideas what happened?
