Selection Techniques

[ ]

Provide a point technique to allow the user to identify a point as a basis for a subsequent adjustment technique.

[ ]

Provide a point technique to allow the user to select and/or toggle the selection state of any selectable element, except one that may also be activated or have its value toggled.

[ ]

If you support a group technique in select mode, support click and swipe variants of it.

[ ]

When the user double clicks the SELECT button (optionally with Ctrl and/or Shift modifiers) on a selectable element and in a scope that does not support multilevel selection, it should first have the same effect as clicking SELECT (with the same modifiers) on that element and then performing the default action.

[ ]

If the user may also activate a selectable element or have its value toggled (for example, a push button or radio button), when the user clicks SELECT on it or presses Select (or Space or Ctrl Space) with the active cursor on it, activate or toggle it instead of selecting it. Such elements may be selected by use of a group technique that includes them in the group of elements to be selected.

[ ]

When the user presses Cancel or Escape, undo any incomplete selection operation. The application must ignore subsequent key and button releases until the user releases all keys and buttons.

[ ]

When the user presses Cancel or Escape during a range selection, deselect all elements in the range.

[ ]

When the user presses Cancel or Escape during a touch selection, leave the selection state of all the elements as they were prior to being touched.
