In a previous email I mentioned the idea of a "menuonly" option to
'completeopt'. I realized today some other reasons why this is important:
1. If I want to view the "info" of a menu item (which would contain the
kind of information Visual Studio does when I hover over menu items), I
need to be able to select the menu item first. If there is only one
completion, I won't be able to view the "info" for that item.
2. Many completion plugins seem to be popping up function prototypes in
the menu. If I want to view them rather than complete them, and there is
only one prototype, then the menu won't come up.
3. The menu itself is a big new addition, IMPO, to Vim; and thus it
should be, like the rest of vim, configurable.

What's your take on the single/double clicks on the menu?

If you're in "-- (insert) SELECT --" mode, and you hit ESC, Vim goes
back to INSERT mode, rather than NORMAL mode. So I don't see why ESC
wouldn't escape the "Completion Mode" and go to INSERT mode, instead of
going to NORMAL mode as it does now. Just a thought.

I'm not sure if you're referring to the "<c-x><c-o><c-p>" idea; but if
you are, and saying that it wouldn't work, maybe you could add something
like "menuonly" option to 'completeopt'. This option would popup the
menu, without inserting any text, and ready for the user to type in that
