I meant to press Alt+F4 to close a window, but I accidently pressed the F5 key instead. When I press the Alt+F5 key, it makes my screen flicker or go black, but it comes back again. I'm curious as what this key combination does. I thought this would be the best place to post my question since it did something with the video.
Any help would be greatly appreciated!!
I do not know of any command mapped to Alt+F5. Fn+F8 is the key combination to switch from LCD to external monitor.
You can disable this function in the rigistry,
Change the REG_DWORD value for the HOTKEY (default 474) to 0
It's "Switch amongst displays" at ATI Control Panel, Displays Scheme.
