Click on the button in the display window
This action brings up an editor that appears to the right
To change the word “about” to “info” for example, type it in the “text box” of the editor.
Once you have created a screen for the button to access, link the button to that screen under the “Select Screen” option of the editor.
Click the “add button” button in the display. A new button editor will appear to the right once you perform this action.
The Screen name which is always required is “Home Screen”. Do not change that.
