After editing that sentence a couple of times, I completely changed the 
meaning into something quite confusing.  A symbol *always* refers to a 
string.  That should read:

The symbol argument should refer to a string that is the name of a 
method.  To create that symbol you take the method name and put a ":" in 
front of it.

I hope that helps.
