Kinda like trying to flip just the right toggle switch and avoid flipping the wrong one?
Just because it's on a touchscreen doesn't mean it has to be tiny and hard to touch. A 17" touchscreen could have fewer controls than the same hardware panel. And the controls could be bigger on the touchscreen.
It’s not like trying to flip just the right toggle. You’ve flipped it thousands of times and memorized its exact location through haptic memory. You gently feel the surroundings to ensure your hand is in the right location and then you make the decisive motion with your fingers. You don’t need to look while doing this. This is how hands work. This is how you type. I wish people would stop pretending they don’t understand this.
Many switches are flipped once or twice on takeoff, then again before or after landing. Depending on the plane (small GA aircraft or airliner or anything inbetween) there could be 4 or 5 switches to flip in total before takeoff, or 30-40. One of the most ubiquitously used controls in aircraft are concentric rotary encoders though, with a button integrated in them if you press the top of the encoder. Those are used to do menu navigation in the GPS units used in many planes, or for altitude/heading selectors in autopilot units.
Worth mentioning that these days GPS units seem to be getting touchscreens but usually still aren't losing the physical buttons.
