Tabbing between subforms

[Lauren]

I have a main form with two subforms nested in it. Since
my users don't understand subforms, I'd like them to be
able to tab through all the controls effortlessly.
However, once I tab after the last control in my first
subform, Access automatically take me to the next record
in the same subform rather than the first control in the
second subform. I know I can hit Ctrl+Tab to advance to
the next subform and then the main form but is there a way
to program this into the form so my users won't have to do
that? Any help will be greatly appreciated.

Thanks!
Lauren
