4. Exportable links to LaTeX
5. Utility functions for dealing with bibtex files and org-files
+Some additional features include
+1. Get minibuffer messages for the cite/ref/label link under point
+
+With helm integration (default) you can:
+
+1. C-c ] to insert a citation link
+ in helm-bibtex
+ - Enter to insert or append citation(s)
+ - C-u Enter to insert an alternative cite link
+ - C-u C-u Enter to replace the citation at point
+2. C-u C-c ] to insert a ref link with helm completion
+3. C-u C-u C-c ] to insert a label with completion
+4. M-x org-ref to get a helm completion buffer with link checks, utilities and export options

+** Messages for context under mouse pointer
+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.
