There were a rash of concerns (though no incidents that I recall) because pilots often leave a hand on the throttle to have a sense of what the aircraft is doing. A sudden movement could mean a change in flight mode or a level off, or a stall.
By contrast Airbus's non-moving throttles are just shiny switches. They have detente settings for each mode. They could just as easily be a set of toggle switches.
If all three fly-by-wire modules concur that you are not, in fact, a complete moron, the airplane will consider your request.
Then again, it would have been much cooler if there had been a "Kirk chair" right in the middle and scantily clad "ensigns" scurrying about.
i hate that auto-full screen though.
gestures seem to work fine. not backwards for me.
Do not, under any circumstances, drool on the buttons.
