Very well.

Indeed, probably not at all important. I'm just saying the parallel 
seems very rough.

Which might or might not be important from the standpoint of trying to 
unify different behaviors in Emacs, to make them more "regular".

The original justification for this binding (authored by Joao) was that 
by using it we indicate that the Xref buffer is used for "completion" 
(picking one result), rather then iterating over multiple matches.

That's why it's TAB, because "TAB completion", apparently. Overall, it's 
not obvious, but it kinda makes sense.
