Horizontal to Vertical Type

Before using the Type tool (T), you can change from the regular horizontal Type tool to the Vertical Type tool by holding down the Shift key before clicking on the artboard (notice your cursor changes direction). As you may have guessed, the Shift key also works the opposite way if you've selected the Vertical Type tool from the Toolbox. The Vertical Type tool will change into the regular Type tool when you Shift-click.
