How do you open the cargo door?

Shift E + 2

Shift-E-1 opens crew door. Shift-e-2 Closes crewdoor, Shift-e-3 opens crew door, shift e-4 closes crew door. I can't get the cargo door to open.JRR

Umm, you never triggered the second door, all you did was open and close the first door. There aren't even four exit triggers! It's difficult to get the 'select' part of 'Select Exit' to work properly. Re-map your exit command to a single key or button. Now, press and hold your 'open exit' key (mine is mapped to 'D'), while you press and hold the number key (Only 1 or 2, not 1-4, as MANY believe). Then release the 'open exit' key while you are holding the number key that corresponds to the door you want to open.
