Adjustment Techniques

NAME

Adjustment Techniques — Reference

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.

When to Use

If you support a group technique, support its corresponding adjustment technique variants.

A point technique
An associated group technique
Another adjustment technique associated with the same group technique
A margin or multilevel technique associated with the same group technique (for example, allow only the range adjust click technique to be used after a point, range [click, swipe, click adjust, or click swipe], or a range margin/multilevel technique)
