There is no single hot key to change the track in one stroke, but on most if not all skins, if you bring up the player controls, somewhere on the control bar, usually the far right, there are some small icons. One looks like a speaker, click on that and it brings up the audio interface where you should be able to select the audio track and the subtitle stream. No need to have 2 versions of the file!
