Thanks for your response. Yes, I know that method. But, actually, that wasn't my question:
How can I switch between them using a hotkey ... or a script ... or some other command?

(BTW: other Internet sources list a command line entry of the form <path>\igfxcfg.exe\SchemeName:<profile name> for controllers a couple of years back. Mine is a new HD Graphics 3000.)
