How to navigate between procedure / function heading and main code

Question

If I have my cursor on a procedure or function definition, is there a quick way to navigate to the beginning of the main code (begin) for the procedure or function, skipping over all the embedded procedure and function declarations (and preferably also navigate in the reverse direction)?

Answer 1

Ctrl+Shift+DownArrow or Ctrl+Shift+UpArrow will jump between declaration and implementation sections in the same unit.

You can find the keyboard key mapping documentation here.
