If you are running in kiosk mode then the keyboard option wont work.
You will need to split your pres into two custom shows - the main show with
automatic transitions and a one slide pause show with no transition. In the
main show add action buttons to h/link to the pause custom show (remember to
tick show and return) and an action button in the pause show to "end show"
In set up show choose show > slides > custom show (the main show)
