There is also a different way of editing the checker positions. You can drag and drop checkers around the board while you're holding down the Ctrl key on your keyboard. Press the Ctrl key and hold it down. Then left-click the checker you want to drag to another point and drag it with the mouse, (while holding down the Ctrl key and the left mouse button), to the destination point. You can drag checkers to open points or to points where you have checkers of the same color. You can also 'hit' opponent blots with the drag and drop edit method.
This method of editing comes handy when there is just a small adjustment to be done in the position.
