Stupid Question...?

[kharrisma]

I have a 7" diagonal touchscreen display that at the moment is hooked up to the Raspberry Pi 4, and as currently set up displays only the Linux terminal screen.  While this is useful on occasion, it would be more useful to use it for Klipperscreen or even the Raspberry Pi OS (for things like cloning the uSD card to back up the system), and even more useful if I could use all three and switch back and forth between them as needed.  My question would be IS there a way to shift between terminal, Klipperscreen, and Raspberry Pi Os using the same display for all of them... some keyboard command that will change what is being displayed, so I can switch back and forth between them as needed... or do I have to pick only one and stick with that?  I'd prefer to have access to all three using the one display just for the convenience, but if that's not possible, then I'll have to decide which is *most* useful and go with that one, and use work-arounds for the other two.  What info I've been able to find is often contradictory and incomplete, mentioning maybe two but not all three.  Figured I'd check in here first to see if someone's already figured this out before wasting a lot of time figuring it out on my own.  Much appreciated!

If you use the key combination, Ctrl-Alt-F1 will drop you to the bash shell (Pi OS) and Ctrl-Alt-F2 whill bring back the KlipperScreen.

It used to work. Let me know if it does not any more.

Is it really nessesary to use so small screen for all this things?
1. I would use this screen only for Klipperscreen
2. For raspberry pi os I would use  original "raspberry pi os" remote desktop
3. On Linux level, I would use SSH connection via putty

For points 2 and 3, You can use any devices, cellphone, Tablet, PC etc.

Thanks, Nikos... I'll try those next time I fire it up.

Sergey, I don't really want to use it full-time for anything but Klipperscreen; what I was trying to find out is if it's possible to switch back and forth, or whether if I commit to install Klipperscreen, I lose the ability to access Linux terminal on the small display.  Ordinarily, I'll just use my laptop to access things, but I don't always want to start the laptop - - having the small display will give me access right from the printer minus the laptop, should I want to do things that way.  Wouldn't be my primary access for terminal or RasPi OS, it would just be nice to have the capability if needed.  Currently looking into RDP or similar to run RasPi OS from the laptop... again, just wanted to know if switching was possible or if I'd be locked into a single use, such as Klipperscreen OR Linux terminal, etc.
