Many users take advantage of "double binding". Based
on evidence in the text and within the application itself it
seems the feature of multi-key binding was to allow for
the different keyboard preferences. (Those who prefer
the arrow keys and those who grew acustom to FPS
keyboard arrangements.) In addition to the use of two
players on one keybaord.
Now however, users bind a single function to two keys
and use them both in gameplay to u-turn rapidly. This
appears out of sync with the structure of the game and
outside the intended use of the feature.
While not a component failure bug, it is an "unintended
feature." If it's not in the spec it should be fixed.
