I am new in AutoIt. I have run the notepad by using the following code in AutoIt:
Run("notepad.exe")
Now I want to quit the application by using "ALT+F4". How to press "ALT+F4" with AutoIt tool?
You'll want to check out the documentation for AutoIt - which is pretty good.
The one you're looking for is: https://www.autoitscript.com/autoit3/docs/functions/Send.htm
Keep in mind that you want to make sure that the window is active or that you're targeting the window.
With that, I recommend using this : https://www.autoitscript.com/autoit3/docs/functions/ControlSend.htm
ControlSend() works in a similar way to Send() but it can send key strokes directly to a window/control, rather than just to the active window.
