I can't seem to figure how to overcome Word's annoying notification popup. After I press Replace All button, a notification pops up "All done. We made 3 replacements."
If I press the Enter key, it goes away. However, simulating the Enter or Return keystroke via KM does not seem to work.
The Press Button action is actually synchronous to the button, so the engine does not proceed until the action of the button press completes, which may be instantaneous or may be after the target application finishes processing whatever the button causes to happen, depending on how the application is written.
