A click can be issued by having the mouse pointer dwell in a given spot for a specified delay. In this mode, the click-type is determined by the ClickType window, Dwell Click applet, or by the direction in which the user moves the mouse after the dwell time has elapsed. The click-type can be single, double, drag or right.
The Dwell Click panel applet can be installed by right-clicking the GNOME Desktop menu bar / system panel, selecting Add to Panel, choosing Dwell Click and clicking the Add button.
