Amazing.
Let's see. I take my office-mate's LaTeX manual (I never use LaTeX myself),
and look up ``\caption'' in the index: p. 59, ...
Ok, p. 59: 
	The caption on a figure or table is made with a \caption command
	having the caption's text as its arguments. This is a moving
	argument, so fragile commands must be \protect'ed (see Section 2.2.3).
Now let's look up \cite: p. 73, 188
p. 73: looks complicated, let's try the other first.
p. 188:
	\cite[text]{key_list}
	The key_list argument ...
	...
	If present, text is added as a remark to the citation. Fragile.


I know, this newsgroup is for beginning as well as for experienced users,
and the TeX and LaTeX manuals are not the most readable books around (by
necessity), but one could still make at least the most elementary attempt
to figure things out oneself --- we've had postings about Reading The Fine
Manual before.
