Calc: Make comments appear on mouseover/hover only

As the title implies, I would like to make comments in a spreadsheet that only appear when I mouseover the related text. If I have to make it a clickable link, that will work too, but I would prefer a mouseover function. Is there a way I can do this?

I think it is the default mode.
But for change, select the cells, right-click and disable show comment.
