How to execute code on cursor move

[Suvayu Ali <fatkasuvayu+linux@gmail.com>]

Hi,

I want to check a text property and display in the minibuffer depending
on context (in my case, on an org-link).

This is what I have so far (working):

(add-hook 'post-command-hook
	  (lambda()
	    (if (eq (get-text-property (point) 'face) 'org-link)
		(display-message-or-buffer
		 (get-text-property (point) 'help-echo)))))

Is using the post-command-hook a good idea?  Is there something better?
As you can see, I'm trying to get the link target; are there better ways
to do this?

Thanks for any ideas.
