Why do you need screenshot button for programming? How many times do you press it? You can just use fn button for that.

People are programming on a 36-key keyboards just fine and they don't miss any keys. It's easier to press fn + something than reaching out for screenshot button, which is usually far away. That way, you don't have to move your hands.

15 years of mouse-free professional programming and never in my life have I touched these.

The screenshot hotkey combo is etched into my brain at this point.
