Command UI contexts are associations between a GUID and a command that affects the UI. It is monitored by the SVsShellMonitorSelection service and set by VSPackages as necessary. Typical uses of the command UI context are to activate a particular mode such as design mode or debug mode and to selectively display a toolbar or menu command. To toggle the state of a command UI context, call SetCmdUIContext.
