In the MAC OS X Lion System, users turn on the three-finger drop gesture, discovering that it is only possible to open the window of the current application, but not to other inactive programs. But sometimes we want to open the windows of other applications without switching the application, so what do we do?
Workaround:
method One: 1. Move the mouse pointer over the Dock bar to point to an application.
2. Use the "three-finger down gesture" to list all the windows of the application (in fact, the same effect can be achieved by using a four-point slide gesture).
Method Two: 1. The application that points the mouse pointer to the Dock bar.
2."two refers to the touch pad two times, or you can list all the windows of the application you are referring to. If your Mac doesn't have a touchpad (some older Mac), you can do the same with the Control+↓ method.
This is how you can use the three-finger down gesture to open the other application window without switching the application, and interested users may try it on their own.
