Area Adjust Click Technique

Reference

Description

The area adjust click technique is an adjustment selection technique in which an area of elements already identified as the current selection region can be adjusted by identifying an adjustment point.

Mouse-based area adjust click technique
Click the ADJUST button at the adjustment point.

Keyboard-based area adjust click technique
With the cursor at the adjustment point, press the Shift Select, Shift Space (unless in text), or Ctrl Shift Space keys.

When to Use

Recommended
Support the area adjust click technique as an alternative to the area adjust swipe technique when the area adjust swipe technique is too cumbersome to use.

Guidelines

Required
When using the area adjust click technique, and the adjustment policy is to reselect:

  1. Determine the new selection region to be the area determined by the anchor point and the adjustment point.

  2. Enlarge the new selection region to include the anchor element or anchor region, if indicated by the anchor inclusion policy.

  3. Enlarge the new selection region, if indicated by the end-point inclusion policy, to include the element, if any, at the adjustment point.

    4. Required
    When using the area adjust click technique, and the adjustment policy is to enlarge, make the new selection region larger than the following:

    1. The current selection region

    2. The region determined using the reselect adjustment policy

      3. Required
      When using the area adjust click technique, and the adjustment policy is to balance:

      1. Move (if necessary) the anchor point so that it is at the corner of the current selection region farthest from the adjustment point.

      2. Determine the new selection region to be the area determined by the new anchor point and the adjustment point.

      3. Enlarge the new selection region to include the anchor element or anchor region, if the anchor point is unchanged and if indicated by the anchor inclusion policy.

      4. Enlarge the new selection region, if indicated by the end-point inclusion policy, to include the element, if any, at the adjustment point.

        5. Required
        If the current selection region does not include an anchor element, or if the anchor element is no longer in the selection region, identify the anchor element to be the element, if any, in the region nearest the anchor point.

        Required
        After a mouse-based area adjust click technique is used, place the active cursor as follows:

        1. If it is a text or graphics cursor, at the point at which the ADJUST button was clicked

        2. If the selection region contains one or more elements, on some element within the selection region

        3. If neither of the above, on the currently cursored element in the selection scope
