Variable: overriding-local-map
overriding-local-map is a variable defined in keyboard.c.
Value
nil
Documentation
Keymap that replaces (overrides) local keymaps.
If this variable is non-nil, Emacs looks up key bindings in this
keymap INSTEAD OF keymap text properties, local-map and keymap
overlay properties, minor mode maps, and the buffer's local map.
Hence, the only active keymaps would be overriding-terminal-local-map,
this keymap, and global-keymap, in order of precedence.
Probably introduced at or before Emacs version 19.23.
