`\cite` (without notes) is the same as `\citet` in author-year mode,
whereas in numerical mode, it is the same as `\citep`.  The starred
version, as well as the one or two optional notes, may also be used.
This syntax has been retained for compatibility, but is no longer
encouraged.

the full author list, and not just the abbreviated one.  These macros
may take one or two optional arguments to add some text before and
after the citation.  Multiple citations may be made by including more
than one citation key in the \cite command argument.

This command prints the citation number, without parentheses, even in

intended to be able to refer to citation numbers without
superscripting them.

This command allows arbitrary text to be placed in the current
citation parentheses. This may be used in combination with
`\citealp`.  For example,
