How to Access the Caps Lock Key on an iPhone

On an iPhone, the Caps Lock key can be accessed by following these steps:

1. Open the app where you want to type in all caps (such as Notes, Messages, or Mail). 2. Tap on the keyboard to bring it up on the screen. 3. Double-tap the shift key (the upward arrow on the left side of the keyboard). This will turn on Caps Lock, and the key will change to a darker color to indicate that it is active. 4. Type the letters you want to appear in all caps. They will be displayed in uppercase letters as you type. 5. To turn off Caps Lock, either double-tap the shift key again or tap the shift key once to switch back to lowercase letters.

Note: These instructions may vary slightly depending on your iPhone model and operating system version.
