Good catch. Things in parentheses are just examples though; my point
is that there is a hierarchy of layers and each higher layer may
choose to intercept and handle certain keystrokes before they ever
reach the lower ones. When debugging an “I press a key and do not get
the expected effect” issue, it helps to understand exactly on which
layer you expect an effect, and which layers above might have a say.
