How to place a checkbox in a cell

Friends,

I realize that its verry basic. But i cant remember how to place a checkbox in a cell (any cell).
The method i seek is not a devellopers modus. That places a checkbox on the sheet or form in Exel.
What i seek is just a checkbox in a cell. So i can place in all cells in a column chechboxes.

I hope it is clear what i want.
