| Zerene Stacker can also be made to simulate keystrokes and mouse actions by itself, even on Windows systems. This is useful for driving third party applications that are not prepared to be launched or controlled by command line actions. | Zerene Stacker can also be made to simulate keystrokes and mouse actions by itself, even on Windows systems.

| **Caution:** Be sure to use press and release events in matched pairs. If you tell the robot to press a key but not to release it, then the computer will continue to act as if the key is held down, even outside Zerene Stacker. The resulting behavior can be quite confusing, particularly if the key that's being "held down" is a modifier like Shift or Ctrl. | **Caution:** Be sure to use press and release events in matched pairs.

| + | **Note:** The simplest way to determine screen coordinates is use your computer's screen capture facility to grab an image of the entire screen, then pull that image into Photoshop or some equivalent program. Pixel coordinates reported by Photoshop, with 0,0 at the upper left of the screen, are the same coordinates needed by Zerene Stacker's robot facility. | ||
