@tvaziri To be fair to your wife, I’ve been using Apple computers since I was five and… I still can’t really use -TAB. It’s a broken model. I never want to switch from application to application; I always want to switch from window to window.
I use four-finger swipe-up swipe-down, which is not as convenient as alt-tab on Windows toggling between windows but is closer than the -TAB shortcut.
