To add a button for the main menu:
Open the menu where you want to add the button and choose Project > Add Title Menu Button.
A button labeled “Title Menu” appears on the menu. It appears in the default style of buttons for the theme you are using.
Click the button once to highlight the text, and then type a new label, such as “Back to Main Menu.”
An in-place control (shown below) appears below the button when you click it. Select a new typeface, font style, and font size for the button label, if you want.
