I agree with your first paragraph but not the second. What frustrates me is any sort of override of my keyboard keys – 100% of the time when I press backspace, I intend to delete one (1) character behind the blinking cursor. Not a whole word, not perform undo, not anything else. One character. (Alternatively, if text is selected, then of course I’d like to delete the selection.)
