Text Box Highlight

I have a text box that uses add text to, they do not replace the text, just add to it.
The problem is that when the text box gets focus, all the text is highlighted and when the user starts typing it replaces the text in the box.

Is there any way to change the way a text box behaves when it gets focus so that the text isn’t highlighted?

An alternate is to use the Text Area component, the problem with this is that it has multiple lines and when the user presses Enter it creates a new line when I want it to submit the change.

Any ideas?

OK, I just figured it out.
The Formatted Text Field component behaves how I want it to work.
