I know this seems simple, but I'm trying to copy a section and paste it to another area. I want to copy from a specific measure, but how do I select or highlight from a particular measure. The grid lines are visible vertically, but doesn't go straight down through the region. If it did it seems you could select from any measure easily. I'm missing something here. Thanks.

Hi sus4, the video courses here on Logic pro X will show you everything you need and more! In this case, use the Marquee tool to select part of a region and option-drag the marquee selected section.

Thank you Rounik. Got it. The video course you're referring to, are they free?
