alt+shift+a = toggle_avatar_invulnerable
alt+shift+b = pass_one_hour
alt+shift+c = unpass_one_hour
alt+shift+d = sunrise_sunset
alt+shift+e = pass_one_minute
alt+shift+f = unpass_one_minute
alt+shift+g = toggle_sun
alt+shift+h = toggle_wind
alt+shift+i = toggle_storms
alt+shift+j = toggle_avatar_fast
alt+shift+k = toggle_avatar_fly

Hidden teleporters:
Locate the fence without a gate behind the Avatar's house. Climb on the nearby training dummy and jump over the fence. Find the level hidden near a bush by the large tree. Pull the lever to find teleporters that will equip your character with armor and allow travel to various places in Britannia. Note: You can not return by teleporter once you leave.

Invisible to monsters:
Press B to open your backpack and attack monsters. They will ignore you as long as the backpack remains open. Note: Drag the backpack to the edge of the screen for a better view.

Hint: Body parts in refrigerator:
While in the Avatar's house, go to the kitchen. Look around for a refrigerator. Open and close the fridge door ten times. If done correctly, the last time you open the fridge, you will find many skinned body parts inside.

Hint: Kill Lord British:
When you start, go to the refrigerator find the rat poison, then use the breadmaker. When you get to Britain, go to his secret dining room. Replace the bread with the poison bread. Lord British will eat it and die. Note: Save before doing this since the guards will kill you.

Glitch: Fish stuck in elevator:
In Hythloth, the elevator in the middle of the pool of poison water may get a fish stuck in it. If this happens, you cannot get on it to get to the yellow stand for the statue. Also, when you try to make the elevator come down it goes up after about three seconds, so you cannot reach it in time.
