revealing clips in timelines...PP4 can we do that?
 

When I click on a clip in the timeline, there is a command to reveal the clip in the project. Very handy!

And, there are times when I want to figure out where I have used a clip in the timeline, but don't know/remember. Is there a way to choose a clip in the project and discover where I have used it in my timelines/sequences?

Right click on the clip in the timeline and select 'Reveal in project'

For the next question, look at the image:

Rockin! That image spoke (and saved you) 1000 words!
 

thanks! I will be using that one a lot!
