* Keymaps and keybinds.
* Within a keymap, keys are bound to a `struct key'.
*
* Normally, `the_funcs[akey.vector][akey.code]' is the command binding of a
* key. However, the akey.vector == -1, then the binding is to another
* keymap, found by the_maps[akey.code]. The final exception, is that if
* both vector and code are -1, then the key is unbound.
