In Icicles, with `i' in Info, *Completions* shows you the index
entries as completion candidates.  You can visit any number of
them during the same `i' invocation.  (Similarly for `g'.)

Optionally, any of them that have already been visited are
highlighted.

Attached screenshot shows this for input that matches "defun".
