I can't figure out how to switch channel groups via a shortcut / key in EPG-Timeline. Since I have grouped my channels (e.g. movies, documentation, free-tv) it is annoying to always grab the mouse (or navigate via keyboard) to the channel-list to switch to the next group of channels. The "PreviousChannelGroup" and "NextChannelGroup" is not working .
I would like to check my movie channels if there is any interesting movie and if not switch to the documentation channels with just one action. Is that possible?
