  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, MODEKEYEDIT_SWITCHMODEAPPEND,
  39  * MODEKEYEDIT_SWITCHMODEAPPENDLINE, and MODEKEYEDIT_SWITCHMODEBEGINLINE)
  40  * are special-cased to do this.
