Customisation Context Menus

The layout control's built-in Customisation context menu provides most
commonly used customisation operations. This menu can only be used at
runtime in customisation mode.

The menu's commands are context dependent, which means that different
commands are available for different layout elements. These include:
Layout Group Context Menu and Layout Item Context Menu.

Multiple layout elements can be selected simultaneously on a form. Thus,
while menu item descriptions in the tables below refer to a single
selected element, the same descriptions apply to all selected elements.
