The command \\[bibtex-clean-entry] cleans the current entry, i.e. it removes
OPT/ALT
from all non-empty optional or alternative fields, checks that no required
fields are empty, and does some formatting dependent on the value of
! bibtex-entry-format.
Note: some functions in BibTeX mode depend on entries being in a special
format (all fields beginning on separate lines), so it is usually a bad
! idea to remove `realign' from bibtex-entry-format.
Use \\[bibtex-find-text] to position the cursor at the end of the current
field.
Use \\[bibtex-next-field] to move to end of the next field.
