Description

The area swipe technique is a group selection technique in which a rectangular area of elements can be selected or deselected by indicating the corners of the area in a single continuous action. The following describes the steps for mouse-based and keyboard-based techniques:

Mouse-based area swipe technique

Press the SELECT button at the initial corner of a rectangular area.
Move the mouse to the opposite corner of the area.
Release the SELECT button at that opposite corner.

Mouse-based area swipe technique, forcing toggle mode

Press Ctrl SELECT at the initial corner of a rectangular area.
Move the mouse to the opposite corner of the area.
Release the SELECT button at that opposite corner.

Keyboard-based area swipe technique

Hold Shift down while pressing a navigation key. The area is determined by the initial and final cursor positions.

When to Use

Required: Support the area swipe technique only when a common selection in the scope consists of a set of spatially adjacent elements.
