Highlighting text in a text box

One of my students is creating a note taking app and would like the user to be able to highlight the text entered into the text box. I don't see an option for that, but I'm wondering if anyone else has a more definitive answer.



you are correct, there is no such option



AI can not do that but the user can double touch the textbox to highlight

like this:

On the emulator, you do it with a double left mouse click; on a device you do it by a rapid double touch.

This this work for the student?
