How to type Alt+0196
- Make sure Num Lock is on.
- Hold down the Alt key.
- Type 0196 on the numeric keypad. The number row above the letters will not work.
- Release Alt. The capital a with diaeresis symbol Ä appears.
The leading zero matters. Alt+0196 uses the Windows-1252 code page. Without the zero, Alt+142 on the classic CP437 table also gives Ä, but that is a coincidence of the two tables rather than the rule, so learn the four-digit version.
On a laptop without a numpad
Press Win+. to open the emoji panel, pick the Symbols tab and search for "capital a with diaeresis". Or open Character Map from the Start menu. In Microsoft Word you can type 00C4 followed by Alt+X. Some laptops have a hidden numpad on the J, K, L, U, I and O keys that activates with Fn.
On a Mac
Alt codes do not exist on macOS and this symbol has no dedicated shortcut. Open the Character Viewer with Control+⌘+Space, search for "capital a with diaeresis" and double-click it.
In HTML and code
Use Ä in HTML, "\00C4" in CSS and "\u00C4" in JavaScript. See the Capital A with Diaeresis guide for every platform.
