I'm new to macOS. After more than 20+ years on Windows, I got used to toggling between apps using Alt+tab and also using simple functions as 'copy-paste'. So, I switched between the 'command' button and the 'control' button and now it is much better. The only thing I couldn't find so far was how to make a specific shortcut for toggling apps on the app switcher that use the same position of the command+tab? (but as I mentioned the command is now the control).
Edit: Thank you very much. I finally downloaded AltTab and it kinda fixed the problem :)
