How to Get back to TV with Remotecontrol

If I’m Watching TV and press exit on my remote to do something in Kodi like go back to the channel overview, change settings or what ever. I’ts not posible to get back to the TV directly. even the TV is running with sound in background. I have to enter the channel from the channel list again to get back to TV. If I do not remember the channel number or scrolled through the channel list, it need much time to get the channel I’m watching.

Could I setup a fast “Get back to TV” button on my remote?
