I got a question about a week ago from a reader that asked “how do I select the entire clip in iMovie ’08”? Well it took some searching and i found the answer at A New Mac Tip Every Day.
Per the tip
What I realized though is that simply clicking on it will just select 4 seconds of the clip. There is a way of quickly selecting everything though. You just have to hold down “Option” and then click on it. It will then select the whole clip.
