Does anyone know how these strings work, specifically the ones highlighted in bold?

dialog_key
difficulty_key
key
key_default
key_offline
key_online
key_playback_in_progress
key_ready_to_record
key_recording_complete
key_recording_in_progress
key_of_unlocking
mp_game_select_default_key
mp_map_key

I have a working theory that this key (mp_map_key) helps point at the currently selected map in the map list, or perhaps the last in play. I am encountering a crash at the map list menu (Halo 2.5 custom PC engine), this may be causing the problem.

You theory seems reasonable, but I dont see why it would cause a crash.
