The first TAB key press beeps at me, then I get:

I suspect that the confusion comes from the fact that 42._ might be
the start of a Float (note the first blank entry at the top of the
first column), but in any case, the completion only happens
immediately (no bell or list) if the completion is unambiguous. Try
typing 42.tiTAB and you should get 42.times_ (at least I do).
