[OS X Emacs] How to enter accented characters on US keyboard?

[skip at pobox.com]

In Aquamacs Emacs how do I enter accented characters on my US keyboard?  I
would have thought it would be in the FAQ, but I didn't see anything there.
I see an Option Key submenu in the Options menu which looks like it might be
useful, but have no idea where to find out what the various choices mean.

(BTW, I noticed there is a pretty obvious misspelling in the q/a about
installing aspell.  Was that a joke or a mistake?)

Thanks,
