For those of us who would prefer to type the vowels in German words with an Umlaut here is a method I've found that was fully explained. While holding down the "ALT" key, with "NUMBER LOCK" on and using the "KEYPAD". Type 0196 for Ä, 0228 ä, 0203 Ë, 0235 ë, 0214 Ö, 0246 ö, 0220 Ü, 0252 ü and Beta S 0223 ß. The letter appears when the "ALT" key is released. The capital letter is 32 less than the lower case letter. I hope I'm not teaching "grannies to suck eggs".
