The recommended procedure if you don't know how to spell the identifier
is to respond with "Say Identifier". If it will take awhile to program
the intersection into the GPS, you could also ask for a heading.

Yes, but to enter the intersection into your flight plan on your GPS,

you must first know how it is spelled. If you are not familiar with
the
area you are flying in and the controller speaks the name of an
intersection, you may not know where to look on the chart to see how
it
is spelled.

Typically, if you file your IFR flight plan with /G, I think ATC
assumes
that its an IFR Certified GPS and that the intersection is in the
database. I've gotten something like this before, but it was
enroute
and ATC asked me if I could identify the intersection. After I
acknowledged that I could, ATC told me "Direct to" that
intersection.
