Thanks @Tinwarble, actually I was re-reading one of your other threads where you posted this...

In the Keymap editor did you assign it under Fullscreen Video > Subtitle > Show Subtitles?
For codec info, go to Fullscreen video > Other > Show codec info, program whichever button you want.

So now I know where to go in the Keymap Editor to make these changes.

But where in the Keymap Editor, do I make the Guilde Button, take me to the Nvidia Home Screen?
