I have searched through all context menu entries in Windows registry editor (in places like HKEY_CLASSES_ROOT\Directory\Background\sehell) but was not able to find anything linking to the 'refresh' entry. I have come to a conclusion that some entries are hard coded in the OS. My ultimate goal was to assign a keyboard shortcut for such a context entry (like 'Next Desktop Background').
Is there any way through which I can access those entries?
