Special German Letters on Keyboard (ä ö ü ß): Alt Codes + Easy Shortcuts

“Special German letters” usually means the umlaut letters (ä, ö, ü) and the German sharp S (ß).

You’ll see them in common German words and names like Mädchen, schön, über, Straße, and Grüße. These letters can change pronunciation (and sometimes meaning), so it’s worth typing them correctly.
