Hyperlink not woking

I'd like to use Keynote, instead of PPT, but for my lectures, I really need to be able to open local web pages and other local demos.

I've got some demos in my lecture that are programmed in shockwave, some are javascript or java applets in the browser, some are regular applications that I start up via a shell script.

And I really need to run all those demos from the slides.

Do you know any workaround that would let me fire up those demos by clicking on an image on a slide in Keynote?

Best regards, Gabriel

Would it be possible, somehow, to start up a shell script from a running Keynote presentation by clicking on an image?

That also works in PPT (it starts then a new Terminal window, and in that Terminal window runs the shell script.)

The shell script resides on my local disk.

That shell script could then run the applet using appletviewer.

That is something I will need in any case, if I want to switch to Keynote, because a number of the demos in my presentations are

just regular executables (compiled from C source code).

And I really don't understand , why local files should be a security risk -- it's the remote web content that could cause a risk.

The local stuff is something I downloaded deliberately myself, so Keynote/Apple can expect me to know what I'm doing ...
