26 * Mode keys. These are the key bindings used when editing (status prompt), and
27 * in the modes. They are split into two sets of three tables, one set of three
28 * for vi and the other for emacs key bindings. The three tables are for
29 * editing, for menu-like modes (choice, more), and for copy modes (copy,
30 * scroll).
31 *
32 * The fixed tables of struct mode_key_entry below are the defaults: they are
33 * built into a tree of struct mode_key_binding by mode_key_init_trees, which
34 * can then be modified.
35 *
36 * vi command mode is handled by having a mode flag in the struct which allows
37 * two sets of bindings to be swapped between. A couple of editing commands
38 * (any matching MODEKEYEDIT_SWITCHMODE*) are special-cased to do this.
