For your own good and for the good of IDLE, I urge you to try implementing
this by improving AutoComplete. Your approach (as I understand it) both
requires first fixing a delicate bug regarding IDLE's event handling and
messes around with the Shell's namespace. I don't think you will manage to
get such a patch accepted.

Good point.

If you submit a patch which updates extend.txt appropriately, I'll review
