Hi Keith,
Adding an accent to vowels in your Greek keyboard is simple. To resolve your concern, follow these steps:
Step 1: Set the Language.
- Click the Start button, then type “Region and Language,” and press Enter.
- Under Languages, click Add a language, then type Greek in the search box.
- Select Greek.
- After that, select Greek under Languages and click Set as default.
Step 2: Add keyboard.
- Under Languages, choose Greek and click Option
- Under Keyboards, click Add a keyboard.
- Then, choose Greek Polytonic.
After you change the language and add the keyboard, you need to Press Windows key + Spacebar (without releasing the Window key, press the spacebar) to switch between installed keyboards (choose Greek Polytonic).
Update us with the outcome.
