How about adding an option something like "showonly" in 'completeopt', that when set brings up the menu, but doesn't automatically choose the first item? However this should probably be better controlled at per buffer level. There were requests before for this same issue, e.g., someone was trying to map "." to bring up omni-completion menu, but didn't want the first item to be automatically chosen (as it is the case in *all* the IDEs), and the workaround was to include the "." also as part of completion (it solves the problem, but I think is ugly, as you need to type <C-N> or <C-P> twice to get to the real first item or last item in the matches). If there is a way for the |complete-function| to indicate this option, it will solve this problem. -- Thank you, Hari __________________________________________________ Do You Yahoo!? Tired of spam?
