The objective of this Technique is to ensure that people with motor impairments who cannot carry out dragging movements are presented with an alternative single pointer interaction.
Some direct manipulation interfaces allow users to pick up targets and use dragging movements to move them to another position, for example, to change the position of an item in a priority list, or to move a task on a Kanban or planning board.
-Such dragging movements are difficult or impossible to carry out for some users with motor disabilities. The alternative to dragging movements operates the underlying function by one or several single pointer activations. A single tap or click may reveal controls (arrows) to move a target in a stepwise fashion; open a drop-down menu where the drop position can be selected; or allow moving it to an ajacent postion by a swipe gesture.

(Regarding the swipe gesture alternative, note that the swipe gesture alone would not be sufficient since Success Criterion 2.5.1 Pointer Gestures requires that functionality can be operated with a single pointer without a path-based gesture, unless a multipoint or path-based gesture is essential.)
