With Hover Text on iPad, you can move the pointer over text and other items on the screen (such as icons) to view a larger version of them. Or use Hover Typing to display a separate window with a larger version of text that you’re typing.
To use Hover Text, you need to connect a pointing device such as a trackpad or mouse with your iPad. On > Accessibility > Hover Text, then tap Hover Typing.
Turn on Hover Typing.
As you type in a text entry field, a larger version of what you’re typing is displayed.
To temporarily hide the Hover Typing window, swipe on it. It reappears when you start typing again.
Go to Settings Accessibility features for vision on iPad
