 Hi there. I've put together this short screencast tutorial so you can see how easy it is to copy slides from one keynote presentation into the other keynote presentation. I've done a quick mock-up similar to the sort of setup that you've got. So you can see here in Keynote, I've got two windows with two separate keynote files comp1 and comp2. So assuming that you're wanting to copy all of your slides into the first keynote slide. So I'm just going to shift to comp2. If I then just drag the window to the side so I can see thumbnails from the first keynote presentation. In fact, I'll just move it down so you can see. So this is the first keynote presentation and it shows you a thumbnail of each slide in the presentation. And this is the second keynote presentation comp2 and of which I've got one slide here. And really to incorporate all the slides into one presentation, it's just drag and drop. So click the slides that you want to copy in this presentation. Click and drag into the first one. Let go where you want the slides to be. So you can see now in this keynote file, you've actually got both slides there. And just complete that sort of process for all the other files that you've got. And then you'll have one keynote file with all the slides in. I hope this helps. Cheers.
