In computer graphical user interfaces, drag and drop is a pointing device gesture in which the user selects a virtual object by "grabbing" it and dragging it to a different location or onto another virtual object. In general, it can be used to invoke many kinds of actions, or create various types of associations between two abstract objects.
As a feature, drag-and-drop support is not found in all software, though it is sometimes a fast and easy-to-learn technique. However, it is not always clear to users that an item can be dragged and dropped, which can decrease usability.

Famous quotes containing the words drag and/or drop:
“Keeping up with the Joneses was a full-time job with my mother and father. It was not until many years later when I lived alone that I realized how much cheaper it was to drag the Joneses down to my level.”
—Quentin Crisp (b. 1908)
“Man is only a reed, the weakest in nature; but he is a thinking reed. There is no need for the whole universe to take up arms to crush him: a vapor, a drop of water is enough to kill him. But even if the universe were to crush him, man would still be nobler than his slayer, because he knows that he is dying and the advantage the universe has over him. The universe knows nothing of this.”
—Blaise Pascal (1623–1662)
