When in the class implementation section of the code window, I can jump to
a method declaration in the interface section by holding the the ctrl key
down, then moving the mouse over the method name, and then clicking. This
hyperlinks to the method declaration.

Is there any key stroke to do the opposite, move from the declaration of a
method to the implementation of the method?
