OverviewDrag
Dragging is simply the act of "grabbing onto" an item with the mouse pointer and dragging it somewhere else.
To drag something, first position the mouse pointer over the item you want to drag. Then, "grab onto" the item by pressing (and holding) the left mouse button. Hold the left mouse button down while you "drag" the item by moving the mouse. When you've positioned the item where you want it, "let go" of it by releasing the mouse button.
Tip: You can abort a drag by pressing the Esc key.
