Hi,

I want to emphasise text by making it bold and then make it regular when I move on to talk about something else. I can use 'bold reveal' animation to make the entire sentence bold at once, but then what am I supposed to do to get rid of it?

This is probably a no-no suggestion but I would just seperate the animation into different slides, onw with regular text followed by bold then back to regular again.

Another way to do it, if you are working in 2007, is set up the text animation to be bold and the duration in the animation pane, select "Until next click". Then have a second animation (of a small circle or something) that starts "On Click", I used Appear entrance animation. Move the circle off of the slide to the left so that when you click, your text goes back to normal and the circle appears off the slide so noone can see it. I tried to make the circle invisible (no fill and no outline) but that didn't work.

Hope that helps,
