1. Type in your first line of text. The text should appear on the button to the right side of your screen.
2. Click and hold to move the text and place it where you would like it.
3. Next click anywhere within the button shape but outside of the current text box that you have created already so the text no longer has a blue box around it.
4. Now if you type in the "enter text" box on the left, it should appear as a new text element. You can then drag that text to create your second line.
