Method Enable

libraries/lib-menus/CommandManager.cpp:634–651

Enables or disables a menu item based on its name (not the label in the menu bar, but the name of the command.) If you give it the name of a multi-item (one that was added using AddItemList(), it will enable or disable all of them at once

///added using AddItemList(), it will enable or disable all
///of them at once
