CollapsingGroupPanel responds to a number of keyboard actions and mouse gestures at runtime. This section describes the runtime behaviour of CollapsingGroupPanel. If CollapsingGroupPanel or one of its child controls has input focus, then a focus rectangle is drawn around the expand collapse button. When a CollapsingGroupPanel or one of its child controls has focus, the CollapsingGroupBox responds to keystrokes.
The table below details how CollapsingGroupPanel responds to keystrokes and mouse gestures.
