So I just modified GeniusPieTrap's list:

F2 = HIDE LEVEL EDITOR DISPLAY ELEMENTS, OR SHOW DATA IN TEST MODE
F3 = PLAY/EDIT LEVEL
F3 X 2 = RELOAD LEVEL
MOUSE WHEEL = ZOOM
MOUSE WHEEL CLICK = ZOOM RESET
LEFT CLICK = PLACE/CREATE
RIGHT CLICK = DELETE
HOLD SHIFT AND DRAG, LEFT CLICK = BLOCK AREA
HOLD CTRL AND DRAG, LEFT CLICK = HOLLOW AREA
HOLD SHIFT AND DRAG, RIGHT CLICK = DELETE AREA
HOLD ALT AND DRAG, LEFT CLICK = SELECT OBJECTS

• LEFT CLICK = MOVE SELECTED OBJECTS
  
• HOLD SHIFT AND LEFT CLICK = COPY AND MOVE SELECTED OBJECTS
  
• RIGHT CLICK = UNSELECT OBJECTS

HOLD ALT AND LEFT CLICK = USE SELECTED TERRAIN OR DOODAD
TAB = FREE MOVE IN EDIT
CTRL + S = QUICK SAVE

DOODADS

• [R,0-9] = SELECT DOODAD VARIATION
  
• PRIMARY ATTACK = NEXT VARIATION
  
• SPECIAL ATTACK = PREVIOUS VARIATION

thanks bro cheers
