Dear all, the contrib package ox-bibtex.el has a function for jumping to a specific bibtex citation key. The current regex assumes a particular indentation style (leading spaces) and only one space between the CUSTOM_ID key and the value of that key. This small patch (hopefully) generalizes the search regex. I've done only some simple testing but seems to work for my configuration.
