Typically when I decide I want to use code completion to override something, I have already typed part 
of the method signature, but not all of it - I have realized I will need to look up the exact signature, and 
so code completion will be easier since it will do it right.

So, I have typed

public void val[CTRL-ENTER]

in my class, there is a method validateTree() I will override.  I select it and press enter and get:

    public void protected void validateTree() {

Could it detect the rest of the signature on the line and do something more intelligent?
