I'm not too familiar with how emacs handles autoloads. However, I find org-mouse is automatically loaded if I call describe-function and then tab complete after typing "", "org-", "org-m", etc. This seems enough to load the entirely of the org-mouse.el file.
The problem is that this adds a lambda function to org-mode-hook that activates all org-mouse functionality at the next call of org-mode or org-mode-restart. This has two unexpected effects: 1. It changes the behavior of mouse clicks without the user's explicit request. 2. It advise org-open-at-point, with the result that it is no longer possible to get a list of all links in an entry when calling org-open-at-point on a headline. (See separate bug report on this.) I am able to reproduce this with a minimal .emacs config and the most recent git version (after running "make clean && make"). Steps to reproduce: 1. /usr/bin/emacs -Q -l ~/minimal.el where ~/minimal.el is... --8<---------------cut here---------------start------------->8--- (add-to-list 'load-path "~/org-mode/lisp/") --8<---------------cut here---------------end--------------->8--- 2. C-h f org-m [tab] Note that "org-mouse-" functions appear in the completion list. Even if one aborts describe-function at this point, org-mouse has been loaded and org-mode-hook now contains a lambda function to activate the functionality of org-mouse (org-defkey, advice-add, etc.). 3. Open an org buffer for the first time or call "M-x org-mode-restart" in an already opened buffer "C-h v org-open-at-point" now reports the following advice: --8<---------------cut here---------------start------------->8--- This function has :around advice: ‘org--mouse-open-at-point’. --8<---------------cut here---------------end--------------->8--- Also notice that org-mouse features are now active in org buffers.
