Step 5: Click once with the left mouse button.

This is some sample text for our newsletter.
Step 7: Select KWord Press Release by placing the mouse cursor on the left end of the text. Click once with the left mouse button and drag the mouse cursor to the right. Selected text will be white text on dark background.
