Is it possible to switch from Window to terminal and vice-versa (linux)?

Hi,
I have an experiment during which experimenters must interact with the machine to tell if the block was either valid or not. Instead of using psychopy.gui, and its dependencies, I would prefer to use the “inquirer” library inside the linux terminal (GitHub - magmax/python-inquirer: A collection of common interactive command line user interfaces, based on Inquirer.js (https://github.com/SBoudrias/Inquirer.js/)), which works pretty well (I use it in the beginning of the experiment to record subjects information).
Si the question is : is there a known way to switch from the main Window (considering it is in fullscreen mode) to one another window, say the terminal, and, once the interaction has ended, give hand back to the main Window so that the experiment can continue.
I hope I am clear enough.
Best,
Benoît
