Using the text tool type in some text and make sure you fill in the Angle option! The number can be positive or negative, it doesn’t matter.
Click OK to add the text.
Now make sure the color in your Color Palette is the same color as your text.
Now make sure the selection lines are still around the text. Click Ctrl-C to copy it.
