Hello, Just fixed the broken link to org-refer-by-number.el; hopefully this gives others a better chance to actually use it :-)
Please find its short description below. with kind regards, Marc-Oliver Ihm
org-refer-by-number.el – refer to things by number, when direct linking is not possible These reference numbers are added to and kept in a table along with the timestamp of their creation. The reference numbers may then be used to refer to things outside of Org (e.g. by writing them on a piece of paper or use them as part of a directory name). Within Org you may then refer to these things by their number (e.g. "R153"). Later, these reference numbers can be looked up easily. Written by Marc-Oliver Ihm. Link to raw file .
