Is there a way to leave a Keynote slideshow running on the second attached monitor while doing other things on the computer? I use my MacBook Pro to run the projector at my school assemblies and I'd like to be able to switch away from the slideshow without it disappearing.
The only solution I have found that's remotely workable is to augment your hardware list and use iOS to present the keynote so your computer is free to assist your teaching without interrupting the display of the keynote.
This has several disadvantages - one of which is not obvious and continually irks me (the undocumented translation bugs).
However, if you have an iPhone, can present from another iOS device and don't mind the translation limitations - this is a fabulous and very robust presentation solution. One benefit is that you can use bluetooth or wireless and walk anywhere in the classroom while controlling the presentation.
This, unfortunately, does not appear to be possible. See the question comments for more details.
A possible solution is to abandon keynote.
MS Office includes Power Point. Have no idea how this works on Mac.
Keynote has the possibility to save to html. HTML has the possibility to load another page after a X second pause.
Note that you could also add links to next/previous pages for manual forward/back.
This would require that you edit the page to add the header line to automatically load the next page.
I don't know how keynote handles any build-ins and actions. You may be reduced to static pages.
