Pointing device gesture
(重定向自Dragging)
In computing, a pointing device gesture or mouse gesture (or, simply, gesture) is a way of combining pointing device or finger movements and clicks that the software recognizes as a specific computer event and responds in a manner particular to that software. They can be useful for people who have difficulties typing on a keyboard. For example, in a web browser, a user can navigate to the previously viewed page by pressing the right pointing device button, moving the pointing device briefly to the left, then releasing the button.
