You can use a click box to appear between these two text animations.
- So insert text animation - 1 and let it play for the required duration.
- Then add a click box and let it pause th movie just after text animation - 1 finishes.
- You can make your click box to appear on entire slide. Thus user can click anywhere to move ahead.
- Now as insert text animation - 2 after the click box timing.
Thus, once text animation-1 finishes, movie will pause and user will have to click on the slide to move ahead. Once user clicks, text animation-2 will start playing.
Hope this solves your problem.
