When viewing entries in a database in
ebib, some fields of some entries are marked with an asterisk (
*). In my case, these are usually
month field. I don't see a rhyme or reason to the types of entries, nor can I see any common error or mistake distinguishing these marked fields from other similar ones in either the same or other entries.
I know that the manual says
+ is used for multi-line entries, and these are certainly not those.
What does this asterisk mean?
