Using the mouse to move and copy cells is another convenient way to cut, copy, and paste.
Click the cell border and drag the cell(s) to a new location.
You must be precise with your mouse and make sure you’re clicking and dragging the cell border. The pointer will change to a black cross with four arrows when it’s over the cell border.
You can also press and hold the Ctrl key while clicking and dragging to copy the selection instead of moving it.
