If you want to see all the cell comments in an Excel sheet, in one step use

Keys are pressed in sequence, not help down. Pressing again, will hide all the cell comments.
(Cell comments are like sticky notes for cells)
Note in the most recent versions of Excel Comments have been renamed to Notes. The terms Comments is now used for threaded (linked) Comments.
Please note: I reserve the right to delete comments that are offensive or off-topic.
