With two external monitors, how do I move and resize window to a specific one?

Hey friends!

I am just getting back into Keyboard Maestro again and I am trying to replace Startupizer by using KM to auto-launch my daily apps, but I am also trying to put the windows in exact places.

I have a 27in iMac and one monitor on each side of it. What is the best way to move and resize windows so that I can choose which monitor the windows go to? Just replacing Main with External doesn't work.

Thanks so much!

I figured it out! Every monitor has an index. Thank you for the great documentation. I learned that my left monitor is index 1 and my right is index 3.

Woo-Hoo!!
