[toddl70566629]

For the love of all things holy how can i "pop in" the time line in my premiere elements? I cannot find the setting to pop it in and out the time line. I am getting so frustrated googling for the answer! 

Please help. Please

What does "pop in" the time line mean?

Are you asking the same question I had, how to set in/out points to export a part of a video?
