True, and the indexing mistake was my fault... Here goes:

Design #1:
        notepad_1 = start("Notepad") 
        notepad_2 = start("Notepad") 
        notepad_1.write("Hello World!") 
        notepad_1.press(CTRL + 'a', CTRL + 'c') 
        notepad_2.press(CTRL + 'v')

Design #2:
        notepad_1 = start("Notepad") 
        notepad_2 = start("Notepad") 
        switch_to(notepad_1) 
        write("Hello World!") 
        press(CTRL + 'a', CTRL + 'c') 
        switch_to(notepad_2) 
        press(CTRL + 'v')

Design #3:
        notepad_1 = start("Notepad") 
        notepad_2 = start("Notepad") 
        with notepad_1: 
                write("Hello World!") 
                press(CTRL + 'a', CTRL + 'c') 
        with notepad_2: 
                press(CTRL + 'v')

Design #4:
        notepad_1 = start("Notepad") 
        notepad_2 = start("Notepad") 
        notepad_1.activate() 
        write("Hello World!") 
        press(CTRL + 'a', CTRL + 'c') 
        notepad_2.activate() 
        press(CTRL + 'v')
