I made this a long time ago: http://isometricland.net/keyboard/chart-temple-of-elemental-evil-the.php?gam=84&sty=15&lay=1 It is a keyboard chart you can print and keep beside you while playing the game. Let me know if I missed any commands.
In vanilla ToEE, I could assign F10 as a hotkey using control+key. Most other non-letter keys are reserved.
