This cheat will make a targeted NPC complete 'favors' for you. After setting favor state to 1 for an NPC, follow the instructions on the screen. Pressing 'E' on the ground will make the NPC wait at that location, pressing 'E' on a door will make the NPC open that door for you, etc. Pressing the TAB key will set the favor state of NPC you are current controlling to 0 again.
