(I think hindfoot/backfoot = RetroPie)
You can boot straight to the command line everytime if you want – is that what you mean?
You can manage this in the setup menu. So exit Emultation Station with F4. press another button within 5 seconds to stop it restarting), then type “sudo /home/pi/RetroPie-Setup/restropie-setup.sh”
Then look in the setup menu for the option to boot to the command line.

When pulse F4, came to the terminal. I have to put the Login. You said that pressing F4 and I press another button within 5 seconds.
Press the button you press on the keyboard, passes 5 seconds and returns to the home screen. It is not retained in the terminal.
