>I could NOT do it at all with the keyboard,
Keyboards have a problem with what is called the "rollover limit",
which is the number of keys that, when held down together, interfere
with each other so that the software cannot see them all. Most
keyboards have a rollover limit of 3, which means that certain 3-key
combinations don't work. For instance, I cannot get W E and PageDown to
work together, so I can climb while accelerating and turning right in
an aeroplane, but I can't dive while doing the same. Different
keyboards have different 3-key combos that don't work.
I have ordered one of these, which has a rollover limit of 6:
