399 %A First author name only.
400 %e Works like %a, but on list of editor names. (%2e and %E work a well)
402 It is also possible to access all other BibTeX database fields:
403 %b booktitle %c chapter %d edition %h howpublished

416 %< as a special operator kills punctuation and space around it after the

419 A pair of square brackets indicates an optional argument, and RefTeX
420 will prompt for the values of these arguments.
