Well... when you fold the source code you can't see it. When
you can't see it you can't understand it and as rasult you
can't track it ;-)

Do not take it too seriously, but emphasis on "too seriously".
Again und again I must read not own sources (C and C++), too.
For navigation in {}-hierarchy I use with love this piece of
lisp code:

;; define function to match a parenthesis otherwise insert a '~'
(defun goto-match-paren (arg)
   "Go to the matching parenthesis if on parenthesis otherwise insert '~'."
   (interactive "p")
   (cond ((looking-at "\\s\(") (forward-list 1) (backward-char 1))
         ((looking-at "\\s\)") (forward-char 1) (backward-list 1))
         (t (self-insert-command (or arg 1)))))
(global-set-key (kbd "~") 'goto-match-paren)

This allows me to jump to corresponding { or } with '~'

And of course I use mic-paren.el and show-paren-mode.
