an insertion point is where the cursor blinks and u start typing
To place the insertion point inside a cell in a spreadsheet, simply click on the cell where you want the insertion point to appear. The insertion point will show up as a blinking cursor inside the cell, allowing you to enter or edit text or data directly within the cell.
