 * 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.
