URC 7820 remote, how to make it work on other TV functions like "Settings, INPUT, MENU, etc."

The best I can do is get this remote to work with volume and channel up/down.   Its a bit useless

if you need to change the INPUT like HDMI for a game box, or the antenna input for a over the air antenna.

I still have to reach for the TV remote.    Would anyone know if this remote can access other functions of a TV?

My TV is a Vizio E370VP
