Area Swipe Technique

Reference

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

  1. Press the SELECT button at the initial corner of a rectangular area.

  2. Move the mouse to the opposite corner of the area.

  3. Release the SELECT button at that opposite corner.

  4. Mouse-based area swipe technique, forcing toggle mode

    1. Press Ctrl SELECT at the initial corner of a rectangular area.

    2. Move the mouse to the opposite corner of the area.

    3. Release the SELECT button at that opposite corner.

    4. 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.

      Required
      Support the area swipe technique only when discontiguous selections are allowed.

      Guidelines

      Required
      Define the current selection region to consist of the specified area as follows:

      1. Enlarged, if indicated by the end-point inclusion policy, to include the element, if any, at the initial corner of the area

      2. Enlarged, if indicated by the end-point inclusion policy, to include the element, if any, at the opposite corner of the area

      3. Required
        After a mouse-based area swipe technique is used:

        1. Identify the anchor point to be the point at which the SELECT button was pressed.

        2. Identify the anchor element to be the element, if any, within the selection region nearest to the anchor point.

        3. Required
          After a mouse-based area swipe technique, place the active cursor as follows:

          1. At the point at which the SELECT button was released, if it can be placed there

          2. If using an element cursor, on some element within the region

          3. If there are no elements in the region, where the cursor previously was in the scope

          4. Required
            When using the area swipe technique in select mode:

            1. Select all the elements in the selection region.

            2. Deselect all other elements in the scope.

            3. Required
              If currently in select mode, pressing Ctrl SELECT instead of SELECT causes the area swipe technique to act as if toggle mode were in use.

              Required
              When using the area swipe technique in toggle mode:

              1. Toggle all elements in the selection region, based on the toggling policy.

              2. Do not change the selection state of the other elements.

              3. Required
                After a keyboard-based area swipe technique is used:

                1. Define the current selection region to consist of the identified range.

                2. Identify the anchor point to be the initial point at which the Shift navigation key was pressed.

                3. Identify the anchor element to be the element, if any, within the selection region nearest to the anchor point.

                4. Required
