[Orgmode] Toggle 'closed' in org-agenda-log-mode-items

[Nathan Neff]

Hello,

I know that I can set this variable or define a custom agenda view
if I only want to see clocked items in the agenda:

(setq org-agenda-log-mode-items (quote (clock)))

But, I like the way that the 'l' and 'R' keys work in the agenda,
where they show/hide
the log and the clock report.

Is there a way to define something similar for the showing/hiding of
Closed log items in the agenda?

I'm not very good at lisp, so something like this pseudo-code:

(defun org-toggle-agenda-show-closed-logs ()
;; pseudo code ------
if org-agenda-log-mode-items contains 'closed' then
    remove 'closed' from org-agenda-log-mode-items
else
   add 'closed' to org-agenda-log-mode-items
(refresh the agenda view)
)

(define-key org-mode-map (kbd "<f6>") 'org-toggle-agenda-show-closed-logs)

Thanks for any feedback,
--Nate
