The Type Into activity has three input methods: Default, Simulate, and Window Messages. The Default method uses hardware drivers to send keystrokes to the target application, which means it requires the window to be active and visible. The Simulate and Window Messages methods use software drivers to send keystrokes to the target application, which means they can work in the background, even if the window is hidden or minimized. However, the Simulate method cannot send hotkeys, while the Window Messages method can. Therefore, the only input methods that can be used individually for the Type Into activity to enter text and hotkeys in a hidden or minimized window are Simulate and Window Messages. References:
