A third option is to use my FastTab XCMD which appeared a few
days ago on comp.binaries.mac.  FastTab is mostly equivalent
to "send tabkey to HyperCard", but it plays a few tricks to
make things go faster.  It should be able to create a
substantial speedup for this type of stack.  FastTab should help until some
form of "spreadsheet" windoid XCMD
comes along.

Disclaimer:  my bias is obvious.
