[O] Reg Navigation keys in org mode presentation

[Kumar Sadhu]

Hi,
I have recently created a presentation in orgmode. Mouse click is used
to navigate through the bullet points. How can I have this
functionality with space key. That is, when I press space bar, I
should get next bullet point.
How can I do this by changing the javascript?
If its not easy to do this by changing javascript, are there any other
ways to do this?
