It would be convinient to get an item from the completion menu faster than <down><down> .. or typing more characters.
What do you think of prepending each item with a number and add a key-mapping <c-i><idx> to get the idxth item? so <c-i>4 would select the 4th. Would it be convinient to add another mapping space for completions? mnoremap 2 <c-i>2 ? m = omni completion _m_enu ? Or is there another easy way to achieve this ? Marc
