Which key runs which command: the commands’ default shortcuts plus the user’s overrides.
An override replaces all of a command’s keys (an empty list unbinds it). Lookup prefers a user
binding over a default one, then declaration order; Keymap::conflicts lists every chord that
more than one command claims. Chords are compared as the keyboard of the keymap’s platform
produces them (off macOS, Mod and Ctrl are one key).
