Exam UiARD topic 4 question 55 discussion

A developer is creating an automation to interact with five Notepad files. The first digit of the Notepad file name is a number 1-5, depending on the Notepad file. The developer used title='1 writtenNotes - Notepad' as a selector attribute for a Type Into activity for one of the files.
The developer wants to modify the Type Into selector to work for any of the files and only one Notepad window will be opened at a time. How should the title attribute be modified?
