When I find the cell, I want to edit that cell (I want to add text to it);
I can still go through the other cells, but I do not want to edit any of them.
For example, if cell 1 contains text, cell 2 contains text as well, but cells 3 and 4 do not contain any text, I want to edit cell 3 such that it contains text. Cell 4 should remain unchanged.
