it didn't prompt the symbol under cursor. I tried up arrow but i
didn't try down arrow; should've.

I filed a bug report on this issue. I think it should prompt the
symbol under cursor like most other lookup commands such as describe-
function, where the current symbol is shown inside the prompt text.
