My name is Takagaki.

I have a visually impaired daughter-in-law.

I want to make an application for my wife.

I would like to create an application to move the cursor of the text field with pythonisa UI for inputting text in iPhone.

I would like to make a button called the left, the right, the top, the bottom, the text and the end of the sentence, but I can't tell the string injury with the UI. I am in trouble.

What should I do to operate the cursor?
