When I select multiple cells in a spreadsheet that are not adjacent to each
other, I can't see what cells are being highlighted unless I go through the
extra step of changing the cell colors. Sometimes, I want to quickly add up
multiple cells by simply highlighting them. I can't do that unless I change
the color or write in a sum function. For example, if I click on cells A1
and C10 and d25 to add them up, I can only see that my cursor is on the last
clicked cell, so I can't tell if I've highlighted all three cells. It's
driving me crazy and slowing me down. Any thoughts?
