Ailerons could be quickly returned to center with Num 5, but IIRC elevator controls did not have such a shortcut, and you couldn't react quickly if you went too

Ailerons could be quickly returned to center with Num 5, but IIRC elevator controls did not have such a shortcut, and you couldn't react quickly if you went too far off. I wonder why they didn't include auto-centering for keyboard pilots.
