I think we want both the tab completion and tooltip to work at the
same time = not be mutually exclusive. I think we should preserve TAB
for the completion logic and move tooltip to something else to be
consistent. This new tab completion logic is really important. Let's
brain storm about ways of allowing both to coexist.
