Xcode 4 automatic code completion -- how to insert NO into code

If I try to type NO into my code somewhere, it brings up a completion list. The开发者_Go百科 highlighted item in the list is always "noisy", which is a variable that frequently appears in my code. Then I have to move to the right item in the list, because if I hit enter it will insert "noisy".

Is there a simple way to insert NO into my code?

Just hit space after typing NO, instead of enter. It looks confusing because you see the word you don't want there; but if you hit space, it will revert to just the characters you typed.
