Press and hold the left mouse button to select the cells you want to copy. Or press and hold shift and use the keyboard arrow keys to select multiple cells.
Press Ctrl+C to copy to the clipboard OR right click and press copy.
To paste select the cell where you want the paste to begin. Eg it will paste from left to right and up to down.
