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: * (MODEKEYEDIT_SWITCHMODE and MODEKEYEDIT_SWITCHMODEAPPEND) are special-cased
39: * to do this.
