Farshid,
Not certain what you are after, but in the slide transition task pane you
can remove the ability to click to move to the next slide. Under the move to
the next slide section remove the check next to on mouseclick.
Also if you want to remove all possibilities to move to the next slide, be
it using the keyboard or the mouse, you can go to Slide show - setup show -
radiobutton browsed at a kiosk. In that case you would have to provide the
ability to move to the next slide yourself using an action button.
