bibtex-skip-to-valid-entry is an interactive compiled Lisp function in `bibtex.el'.

(bibtex-skip-to-valid-entry &optional BACKWARD)

Move point to beginning of the next valid BibTeX entry.
Do not move if we are already at beginning of a valid BibTeX entry.
With optional argument BACKWARD non-nil, move backward to
beginning of previous valid one. A valid entry is a syntactical correct one
with type contained in `bibtex-BibTeX-entry-alist' or, if
`bibtex-sort-ignore-string-entries' is nil, a syntactical correct string
entry. Return buffer position of beginning and end of entry if a valid
entry is found, nil otherwise.
