I am using a bluetooth logitech keyboard designed for playstation. Unfortunately it doesnt have volume buttons. Is it possible to set hotkeys from xbmx to control the windows master volume?
+ and - should already do the trick for you.
I am aware of the +- buttons to set volume of xbmc, but I would like to change the volume of windows from within xbmc. Workaround could be to set windows volume to max and then use +&- to control the volume. I would prefer to use the +&- to change the volume of windows.
