The key is used allow proper alphabetization of the entries,
also for alternate formatting of some entries.
I do not know about three (or two) argument variants.

\index{entry}
\index[key]{entry}
\index[form::]{entry}
\index[form::key]{entry}
\index{form::entry}
\index[key]{form::entry}
\index[form::]{form::entry}
\index[form::key]{form::entry}
