I want to duplicate actions performed on my main screen on a second screen i.e. mouse clicks and keyboard input.
I have one iMac, with two similar displays. On both displays, I have opened two same programs with near pixel-perfect identical positions on the screens.
How can I achieve this? Does such a task require a programmer?
As an example:
Let's say, I open the Chrome browser, logged-in with my Google username ,on the main screen. On the screen display attached to my Mac, I open another Chrome browser window, this time logged-in as my friend's Google username.
What I want is for anything I do on the first browser (mouse clicks and keyboard) to be done on the second browser, on the second monitor.
