Re: Customizing spread sheet apps.

Thanks for the explanation. Do all have functions *need* to be written in
Emacs Lisp, or could you use Elisp to execute for example Python functions?

At any rate this sounds a lot easier than learning how to edit open office.
Though if someone else would like to differ on that account, do please.

Thanks,
Iain
