On Windows, using the Umlaut alt codes work everywhere including Microsoft Word, Excel, PowerPoint, Outlook, and even on browsers. But options like the shortcut that works only in Microsoft Word.

Please use the comments section below if you have anything to say about these umlauts letters and how to insert them into your PC.


    1. For the Alt Code method to work, you must have the numeric keypad. If your laptop doesn’t have a separate numeric keypad, most laptops have a numeric keypad which you can activate by press Fn + NmLk keys. If that too is not there then you should copy and paste the symbol or use an external keyboard with a num pad.

  1. I entered all the necessary sets on Windows 11 to type umlauts and get an error “No Master Source has been selected” what does that mean ?

  2. I could be naïve but ctrl + shift + ; method did not work for me. However, using the spell correction popped up the correct spelling. Using the alt 0239 method gave me this: ï. However, when I tried to use this in outlook the exact opposite happened. It would be nice to have a universal method.

  3. In summary, if you have Windows and use WORD; to get an unlaut letter, you don’t need a Numberic keypad at all–it’s actually easier without. Just do what the admin said, and you don’t even need to memorize anything else. For example, you want ë to be displayed:

    1. Press Ctrl+Shift+; at the same time and let go.
    2. Type the wovel e and you’ll get the unlaut letter.

    In addition, if you want an accented letter, such as é,

    1. Press Ctrl+’ and let go.
    2. Type e and you’ll get é.

    For capital letters, press the cap locks first.

    Anyway, no numeric keypad necessary.

  4. I used the character map. If you click on the symbol you need, such as the diaresis, or umlaut, it will tell you what key to push and the # you need, so you don’t have to memorize a long list of numbers.

  5. For Windows/Linux: you also can switch to the US-International Layout and then press following combos with AltGr (right Alt):
    + q for ä
    + y for ü
    + p for ö
    + s for ß

    For Mac: You can press and hold a, o, u and then press the shown number to select the right umlaut char (for example press and hold u until the tooltip appears. Release the key and press 2 for ü)

  6. Because Ctrl+Shift+; is not working on my keyboard, I suppose that different keyboard layouts (languages) need different instructions. The semi-colon ; is made differently on my keyboard compared to, e.g., English layout. I then found from MS support that Ctrl + Shift + : (colon) is the right one. And it works on my keyboard

  7. Surely the easiest, if not the fastest, way is to use the Character Map? You need to find the particular font you are using. This gives you a great many different accents.
    Once you have Selected the character you can Insert it several times.
    The weirdest way is to use the Emoji Keyboard. Use Win + ; to bring it up.
    Then on the top line click on the capital omega Ohm sign. Then on the bottom line click on the capital C with a cedilla. This brings up many letters with accents. You just have to hunt for what you want. Though once selected it remembers them, under L within a circle at the foot. In all there are over 600 characters and symbols. You just have to hunt! And I don’t know which font they will appear in.
    All this in Windows.

  8. Best description in detail and easy to follow instructions. It worked – I am using a Word document- Alt 0235
