To change the text that is displayed in the label object, highlight the contents of the Text setting in the properties pane, and type in the text that you want it to display.
Tip: A quick way to highlight all of the text in a setting is to double-click on the left-hand column of the properties pane.
In this case, highlight the words New Label and type in ted@sellersrealty.com instead.
Note: Whenever text is highlighted, anything you type instantly replaces the highlighted text.
