Subroutine jumps which RETURN from hyperlinks
I asked this long ago. At that time there was no satisfactory answer. I therefore pose the question again.
In Keynote, hyperlinks to other presentations (or other parts of the same presentation) are ABSOLUTE jumps not SUBROUTINE jumps. Subroutine jumps remember where they came from and RETURN. This is a HUGE advantage. It means you can construct a presentation from MODULES each containing, say, half a dozen slides. Different lectures can then be constructed by stringing hyperlinks together. Standard good programming practice. There is enormous saving of disk space, because many lectures duplicate slides from other lectures. Ideally a new lecture could be constructed as nothing but a list of hyperlinks, each hyperlink pointing to a pre-stored module. This sensible way of assembling a presentation is IMPOSSIBLE if hyperlinks are absolute jumps. Modules have to remember where they came from, otherwise you are left dangling at the end of the module with no way of returning to the main drag. Notoriously bad programming practice, which is why some computer science gurus advocate BANNING absolute jumps!
What I am suggesting is available in Powerpoint and it is the ONLY reason I am tempted to return to Powerpoint. The Nobel-prizewinning scientist Sir Harry Kroto assembles his presentations entirely by this modular method using POWERPOINT.
If this can already be done in the latest version of Keynote I shall be delighted. If not, how should I pass on the suggestion to those in charge of future developments? The difficult programming work w.r.t. hyperlinks has already been done. It should be trivial to add to hyperlinks a memory of where they came from.
