From vsshell.idl:

HRESULT IVsSelectionEvents::OnCmdUIContextChanged(

);

This method is called by the environment to notify registered VSPackages that a command UI context changed from a Boolean Off to On, or vice versa. Command UI contexts are monitored at the global level by the SVsShellMonitorSelection service. For example, when a command UI context is used to turn on debug mode, the environment notifies all registered VSPackages of this change in mode by calling IVsSelectionEvents::OnCmdUIContextChanged.
