Oh, I know it can be disabled. My point was just that "seemingly
impossible" keyboard combinations can be accidentally pressed
nonetheless. In my case I was trying to hit F12, but instead
force of habit I hit C-A-D instead. Granted, it doesn't happen
often, in fact maybe twice in 3 years, but I was furious when it
did happen... ;o) I could disable it, sure, but then what to do
when there is no solution but to hit the three finger salute?

Oh, I understand that. My whole point is that regardless of a
keystroke rarity, it can be accidentally pressed. Random
accident? Unlikely. Habitual accident, possibly.
