4. Exportable links to LaTeX
5. Utility functions for dealing with bibtex files and org-files
+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
