Thank you for your reply. What do you think of Chris Angelico's points?

What I am most afraid of: that the window that's currently the context "dis=
appears":
	notepad =3D start("Notepad")
	with notepad:
		press(ALT + TAB)
		write("Am I in Notepad now?")

What do you think of designs #3 and #4?

        notepad_1 =3D start("Notepad")=20
        notepad_2 =3D start("Notepad")=20
        switch_to(notepad_1)=20
        write("Hello World!")=20
        press(CTRL + 'a', CTRL + 'c')=20
        switch_to(notepad_2)=20
        press(CTRL + 'v')=20

        notepad_1 =3D start("Notepad")=20
        notepad_2 =3D start("Notepad")=20
        notepad_1.activate()=20
        write("Hello World!")=20
        press(CTRL + 'a', CTRL + 'c')=20
        notepad_2.activate()=20
        press(CTRL + 'v')

I somehow prefer "activate" over "focus" as in my feeling, you'd normally s=
ay that you focus *on* something, so it should be called "focus_on" or "giv=
e_focus[_to]". Can you say, in everyday English, that you "focus a window"?=
 I'm not a native speaker so maybe my feeling is misguided.

Thanks,
Michael
