If you plan to accept audience questions during your presentation the best method for moving from one slide to the next is

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !

if you go to ask a question say ask, there should be something that looks like this. a camera lens.
