How do you double backspace and remove text box (make non-visible)?

I am making a checklist app similar to Google Keep. I have it setup currently where I can type in a TextBox and press Enter/Return and the next TextBox will become visible immediately below it. I am trying to figure out how to press Delete/Backspace to clear the text in a text box and then press Delete again and have it make that TextBox.visible = false, and then shift the focus to the TextBox above it.

Basically, I want to use Enter to add extra TextBoxes vertically descending, and then use Delete/Backspace to remove TextBoxes ascending upwards. Anyone know how to use the Delete button to do this? I am trying to avoid using an actual Button to make TextBoxes non-visible and only rely on the Delete/Backspace key on the onscreen keyboard.

You can make an unlimited number of entries by making them ListView Elements, and use just a single textbox under the ListView for a new Element.

I will have to try that! Will that allow the delete function?
