* Mode keys. These are the key bindings used when editing (status prompt), and

* for vi and the other for emacs key bindings. The three tables are for
* editing, for menu-like modes (choice, more), and for copy modes (copy,
* scroll).
*
* The fixed tables of struct mode_key_entry below are the defaults: they are
* built into a tree of struct mode_key_binding by mode_key_init_trees, which
* can then be modified.
*
* vi command mode is handled by having a mode flag in the struct which allows
* two sets of bindings to be swapped between. A couple of editing commands
* (any matching MODEKEYEDIT_SWITCHMODE*) are special-cased to do this.
