Numpad 1: Save Position - press key to save your position
Numpad 2: Teleport To Saved Position - teleport to the saved position
Numpad 3: Disable AI Enemies - toggle this on and many AI enemies are affected. They may not even appear, some may not be able to attack, some may ignore the player. Try when needed to see if it affects the AI and helps your situation. Probably best used for human like AI.
Numpad 4: Invisible to Leeches - toggle on and when you are near leeches, they will drop but will likely leave you alone.
Numpad 5: Super Jump - when you press this, it will launch you up into the air. Holding it will send you higher and higher. Use this to reach difficult locations. Keep in mind that if you fall from heights, you will die, so use with caution.
