You could use something like the following.

(defvar my-outline-toggle nil
  "Control variable for toggling outlines.")
(defun my-outline-toggle-all ()
  "Show or hide all depending on value of `my-outline-toggle'."
  (interactive)
  (if my-outline-toggle
      (show-all)
    (hide-body))
  (setq my-outline-toggle (not my-outline-toggle)))

And then
(local-set-key [f7] 'my-outline-toggle-all)

This is very primitive and does not try to figure out the current state.

You might also want to try `M-x reveal-mode <RET>'.
