The fastest way to add an umlaut

An umlaut is the pair of dots that appears above certain letters in German and other languages — ä, ö, ü, and Ä, Ö, Ü. In Microsoft Word, the quickest method is to hold Ctrl and press the colon key (:), then when ready type the letter you want to modify. For example, Ctrl + : followed by the letter "a" produces ä. Release both keys after pressing the colon, then type the letter.

This works in Word on Windows. If nothing appears after you press Ctrl + :, your keyboard layout may not support this shortcut — move to the next section for alternatives.

The same shortcut works for capital letters. Ctrl + : followed by Shift + A produces Ä. You do not need to hold Shift while pressing the colon itself, only when you type the letter afterward.

Key Takeaways

  • On Windows, hold Ctrl, press the colon key (:), release both, then type the letter you want dotted — Ctrl + : then "a" makes ä.
  • On Mac, hold Option and press the letter "u", release, then type the letter again — Option + u then "a" makes ä.
  • If keyboard shortcuts do not work, use Insert > Special Character, search for the letter with umlaut, and click Insert.
  • You can also type the letter, select it, then use Format > Text Effects to add a diacritic mark manually.

How to add an umlaut on Mac

On a Mac, the shortcut is different. Hold Option and press the letter "u", then release both keys and type the letter you want to modify. For example, Option + u followed by "a" produces ä. This is sometimes called a dead key — you press the modifier combination first, and the letter appears only after you type the second character.

For capital letters, hold Option, press "u", release, then hold Shift and type the letter. Option + u followed by Shift + A produces Ä.

If this shortcut does not work, your Mac keyboard layout may be set to something other than U.S. English. Check System Preferences > Keyboard > Input Sources to confirm your active layout.

Using the Insert menu when shortcuts do not work

If the keyboard shortcut does not produce the umlaut, you can insert it manually through Word's menu. Click the Insert tab at the top of the ribbon, then click Special Character (on Mac, this may appear as Symbol). A dialog box opens showing available characters.

Type the letter with umlaut you want — for example, "a umlaut" or just "ä" — into the search field. Word displays matching characters. Click the one you need and then click Insert. The character appears at your cursor position in the document.

This method is slower than a keyboard shortcut but works on any computer, regardless of keyboard layout or regional settings. You can also browse the full character list by scrolling, though searching is faster when you know what you are looking for.

Copying and pasting from another source

If you need an umlaut and neither the keyboard shortcut nor the Insert menu works, you can copy the character from anywhere else and paste it into your document. Type the letter with umlaut into a search engine, copy the result, and paste it into Word using Ctrl + V (Windows) or Command + V (Mac).

This is not the fastest method, but it requires no knowledge of keyboard shortcuts or menu navigation. Once you have pasted the character once, you can select it in your document, copy it, and reuse it throughout your work without searching again.

Setting up AutoCorrect for repeated umlauts

If you type the same umlaut repeatedly, you can set up an AutoCorrect rule to replace a straightforward text combination with the umlaut automatically. For example, you could tell Word to replace "ae" with "ä" every time you type it.

Click File, then Options (on Mac, click Word in the menu bar, then PreferencesProofing in the left menu, then click AutoCorrect Options. In the Replace field, type the shorthand you want to use — for example, "ae". In the With field, paste or type the umlaut character — ä. Click Add, then OK.

From that point forward, whenever you type "ae" followed by a space or punctuation, Word replaces it with ä. Be careful with common letter combinations — if you use "ae" for other purposes, this rule will interfere. Choose a replacement text that you will not type accidentally, such as "a:" or "aeu".

Checking your keyboard layout and language settings

If none of the shortcuts work, your computer may be set to a keyboard layout that does not include umlaut shortcuts. Windows and Mac both allow you to switch between layouts — for example, from U.S. English to German — and each layout has different shortcuts.

On Windows, right-click the language indicator in the bottom right corner of the screen (usually showing "ENG" or similar) and select a different keyboard layout if one is available. On Mac, click the flag or language icon in the top right corner and choose a different input source.

If you switch to a German keyboard layout, the umlaut shortcuts will change. German keyboards place the umlaut characters in different positions, and the shortcuts reflect that. If you do not want to change your entire keyboard layout, stick with the Insert menu or AutoCorrect method instead.

Frequently Asked Questions

Why does Ctrl + : not work on my Windows computer?

Your keyboard layout may not support this shortcut, or you may have a non-standard keyboard. Try the Insert > Special Character menu instead, or check your keyboard layout in Settings > Time & Language > Language & Region to confirm it is set to U.S. English or a layout that supports umlauts.

Can I add an umlaut to a letter I have already typed?

Yes. Select the letter, then use Insert > Special Character to find the umlaut version and replace it. Alternatively, delete the letter and type it again using the keyboard shortcut or AutoCorrect rule.

Does the umlaut shortcut work in other Microsoft programs?

The same shortcuts work in Outlook, Excel, and PowerPoint on both Windows and Mac. They also work in most other Windows programs, though some older software may not recognize them.

What if I need multiple different umlauts in the same document?

Set up separate AutoCorrect rules for each one — for example, "ae" for ä, "oe" for ö, and "ue" for ü. This is faster than using the Insert menu repeatedly if you type many umlauts.

Will the umlaut print correctly if I send the document to someone else?

Yes. The umlaut is a standard character and will display and print correctly on any computer, regardless of keyboard layout or language settings. The character itself is saved in the document, not the method you used to create it.
