The TM (trademark) symbols in the post are ridiculously large (at least, they are for me) — screenshot attached.
 

Somehow when I was watching Live TV a menu I've never seen before appeared — I must have accidentally pressed a button or combination of buttons on the remote.

It appeared below the programme banner (at the bottom left of the screen) and was something to do with a selecting device to control — there were about 4 icons in a row, and one of them was "Set-top Box", but I can't remember what the other options were.

Having selected "Set-top Box", which is why I remember that option, I now get five icons appearing in a row below the programme banner:

Start Recording  |  Start Live Playback  |  Recordings  |  Subtitle Language  |  Audio Language

See screenshot attached.

The same menu appears if I press the down arrow ᐁ (below the OK button).

What's driving me nuts is:  1.) I can't now bring up the original 'select device' menu, and  2.)  wondering what the other options are!

I'm using an LM6300, running webOS 4.9.5-14 (goldilocks2-gympie).  If any other info would help, please let me know.

Thanks for any help.
