| * 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. |
