Annoying: Netbeans code completion in comments

I don’t understand why Netbeans performs code completion when you are typing a comment.  If I am working in a java file, typing a comment, and come to a word like “if” or “for”, Netbeans automatically inserts the code completion templates for those keywords.  Shouldn’t it recognize that I am typing within a comment?  Is there a fix for this issue?

EDIT: Another thing that drives me mad: I use Alt+F S to save. Constantly. I’m so trained in doing this that I usually don’t even think about it. In Netbeans, however, this often results in the letter “s” being typed, either because the File menu didn’t drop down fast enough or the S key registered twice. I’ve never had this problem in any other program.
