To Open the Key-in Window
With the input focus in the home position, press <Enter>.
The second and third method opens the Key-in window as a pop-up window at the pointer location. For the second option to work, Pressing Enter Shows Key-in Browser in the Preferences dialog should be turned on. To dismiss the pop-up without entering a key-in, move the pointer away from the pop-up. Also, if the Key-in window is already docked or open, sends the input focus to it.
