                          robot.keyRelease(KeyEvent.VK_S);

Have you tried using AutoIT Scripting?

Also you can try the Robot Handling activity using Keyboard shortcuts like Ctrl+S or something like that.

Tried with AutoIT scripting also but that popup does not have any identity like name,class,id etc.
Ctrl+S saves whole page.

Hi Sager,

You can try with Sikuli java code.
