Sending Keystrokes to Inactive Applications with Applescript

Thanks. Yes, Keynote dictionary supports advancing the slides, which is what I want to do, but it requires you to first activate Keynote to accept the command, unlike PowerPoint. The trick is that I'm trying to advance the slides withOUT activating Keynote. So what I need to do instead is send a keystroke to the window, which I know works because I got it to work in Keyboard Maestro. I can also send PgDn/PgUp to navigate the slides. Does that help?

Thanks. It's a strange use case but has to do with using broadcast software, that allows you to switch between cameras, applications, videos, etc., as part of a Live stream or a recording. Essentially, I would like to be able to advance a Keynote presentation, that IS running, without bringing that presentation to the foreground. Again, I've been able to confirm, using Keyboard Maestro, that it is possible so it's just about finding the window, of the current process, of the keynote application and sending a key to it. Lots of AppleScript objects have the keystroke method but I need to get a reference to the current Keynote application window (when I slideshow is running) and send a keystroke to that.

It turns out, you cannot. The commands in the keynote dictionary require keynote to be in front, ie activated. So I need to send a keystroke either to the process or the window, which appears to be Window 1 so that helps.

I'm a single monitor as well but Keynote now allows you to play your slideshow in a window instead of a full screen, so that's what I'm doing. You go to the Play menu to do it.
