Option "DragLockButtons" "L1 B2 L3 B4"
Sets "drag lock buttons" that simulate holding a button down, so that low dexterity people do not have to hold a button down at the same time they move a mouse cursor. Button numbers occur in pairs, with the lock button number occurring first, followed by the button number that is the target of the lock button. Property: "Evdev Drag Lock ButtonsEvdev Drag Lock Buttons".
Option "DragLockButtons" "M1"
Sets a "master drag lock button" that acts as a "Meta Key" indicating that the next button pressed is to be "drag locked". Property: "Evdev Drag Lock Buttons".
5.4. Drag Lock Buttons
Some people find it difficult or inconvenient to hold a trackball button down, while at the same time moving the ball. Drag lock buttons simulate the holding down of another button. When a drag lock button is first pressed, its target buttons is "locked" down until the second time the lock button is released, or until the button itself is pressed and released. This allows the starting of a drag, the movement of the trackball, and the ending of the drag to be separate operations.
Option "DragLockButtons" "W X Y Z"
This option consists of pairs of buttons. Each lock button number is followed by the number of the button that it locks. In the above, button number "W" is a drag lock button for button "X" and button number "Y" is a drag lock button for button "Z".
It may not be desirable to use multiple buttons as drag locks. Instead, a "master drag lock button" may be defined. A master drag lock button acts as a "META" key. After a master lock button is released, the next button pressed is "locked" and not released until the second time the real button is released.
Option "DragLockButtons" "M"
Since button "M" is unpaired it is a master drag lock button.
