Adjustment Techniques

Description
Adjustment techniques are variants of other group techniques. The user uses
adjustment techniques to adjust the group of elements in the current selection
region. Adjustment techniques have both click and swipe variants, as
follows:
- Adjust click techniques
- The group is adjusted by taking a discrete action at a single adjustment
point.
- Via the mouse
- Click the ADJUST button at that point.
- Via the keyboard
- Press Shift Select at that point (use Space or Ctrl Space instead
of Select if there is no Select key).
- Adjust swipe techniques
- The group is adjusted by taking a continuous action between an initial and
final adjustment point.
- Via the mouse
- Press, move, and release the ADJUST button.
- Via the keyboard
- Navigation augmented by the Shift key.
