Could one make the ?
which appears for an unfound bibtex key into some other arbitrary string or symbol? I have a large document and it is slow searching through the ?
to look for missing bibliographic references. (MWE below, but assume I'm using a referencing style which does not output [?]
for missing references, but simply ?
. I decided to keep the MWE simple however).
Alternatively if this is not possible, or if this is not wise, I'd be interested to learn why.
