Strange... this works for me as well when I am not in my plugin window,
but when the cursor is in the plugin window, it gets completely ignored
(the breakpoint doesn't even get called, no buffer mapping for <C-N> to
hide this, I checked). This beats me, but I think this is because of the
way I am setting completion items. Instead of using the traditional
'completefunc' or 'omnifunc' approach (which involves invoking a
keysequence), I am using the CursorMovedI event to set completions as
soon as user types something (this is because, the whole purpose of the
plugin is to show matches, so there is no point asking the user to press
<C-X><C-U> or any other key). Looks like I need to look deeper into the
problem. Thanks to all.
