Normal animations include:

Open/Close Crew Access (Shift + E)
Open/Close Nose Cargo and Ramp Acess (Shift + E + 2)

Unusual animations (for which you have to assign keys to):

WINGFOLD: opens/closes all upper deck pax doors (Shift + C)
CONCORDE NOSE EXTEND: opens engine cowlings (Shift + E + 3)
CONCORDE NOSE RETRACT: closes engine cowlings (Shift + E + 4)

FSX does not support more than four engines. Default contails are only available for the inner four engines, but contrails for number 1 and 6 engines can be activated by pressing the key (usually after the normal contrails appear at high altitude).
