+Sometimes, when reading a document, I actually use the mouse more than the cursor. This code enables the mouse cursor to trigger a message in the minibuffer about what is under the cursor. I run this on a timer.
+
+The basic idea here is to get the mouse position, and if we can determine there is a character that (point) can move to, we move (point) and run the org-ref-link-message function. Since this runs on a timer, we store the last mouse position, and only run the function when the mouse has moved to avoid getting messages every time the timer runs.
