How to type Ö ö — O with umlaut / diaeresis

Type it on our keyboard

Open the field already filled with ö — type or click more, then copy. No install, works offline:

Codes

Reference	ö	Ö
Unicode	U+00F6	U+00D6
HTML entity	`ö`	`Ö`
CSS escape	`\00F6`	`\00D6`
macOS — Unicode Hex Input	`⌥` 00F6	`⌥` 00D6
Windows — Word	00F6 `Alt + X`	00D6 `Alt + X`

macOS hex input needs the “Unicode Hex Input” source enabled (System Settings → Keyboard). The Windows Alt + X trick works in Word and Outlook; elsewhere use the panel below.

On a Mac

Quick combo: press ⌥U then O.
Press and hold the o key — an accent menu pops up; pick ö.
Character Viewer: ⌃⌘Space, search “o with umlaut / diaeresis”, double-click it.

On Windows

Emoji & symbols: Win + ., switch to symbols, find ö.
Character Map (search it in the Start menu) → find ö → Copy.

With PolyType installed

If you run the PolyType app or browser extension, type the base letter then the diacritic — no layout switch (the directive accents the letter immediately before it):

o;umlaut␣

The instant cycle ;;o also works (repeat to cycle variants). This inline syntax needs PolyType running; without it, use a method above.
