To this effect when you press CTRL + SHIFT + 7 (CTRL + &) and s the character ß should be inserted.
This is what I have come up with:
So far everything works as intended, except that after the run of the script the keyboard layout has changed.
When I exchange the Input command with InputBox there is no keyboard layout change.
Furthermore, the change in keyboard layout happens on the release of CTRL + Shift (the language switch combination for my Windows).
