How do you turn on notifications for a specific user on Twitter?

To turn on notifications for a specific user on Twitter, follow these steps:

1. **Visit the User's Profile**: Navigate to the profile of the user for whom you want to turn on notifications. You can do this by searching for the user's username in the Twitter search bar or by clicking on their profile if you already follow them.

2. **Click on the Bell Icon**: On the user's profile, locate the bell icon next to the "Following" button. This bell icon represents notifications. Click on the bell icon to access notification settings for that user.

3. **Select Notification Preferences**: After clicking on the bell icon, a dropdown menu will appear with notification options. You can choose from the following notification preferences:
   - **All tweets**: Receive notifications for all tweets posted by the user.
   - **Only tweets with live video**: Receive notifications only for tweets that contain live video broadcasts.
   - **Only tweets with highlights**: Receive notifications only for tweets that Twitter deems as highlights from the user's activity.
   - **None**: Turn off notifications for the user.

4. **Choose Notification Preference**: Select your desired notification preference from the dropdown menu. For example, if you want to receive notifications for all tweets from the user, choose "All tweets".

5. **Confirm Notification Settings**: Once you've selected your notification preference, it will be automatically saved. You'll start receiving notifications for the user's tweets according to the chosen preference.

That's it! You've successfully turned on notifications for a specific user on Twitter. You'll now receive notifications whenever the user tweets, based on your selected notification preferences.
