No. On German and Swiss layouts, that key is a dead key: it doesn't type anything by itself when you press it. It's meant to combine with another subsequent keypress in order to yield a whole glyph with a diacritic as in, e.g., backtick followed by "e" giving "è."

It's been a while since I've been at a proper QWERTZ layout aus dem Sprachgebiet over a US QWERTY keyboard, but my memory is that the dead keys have odd behaviors when you try to incorporate them into shortcuts.
