Add a text control to the artboard
Adding a text control to the artboard is the same as adding any other control to the artboard. The difference is that if the control is one of the special types of text controls, Microsoft Expression Blend immediately enters text-editing mode, so that you can modify the text.
To add a text control to the artboard
With a document open in Design view of Expression Blend, select a control that displays text (such as a Button, a TextBlock, and so on) from the Toolbox or from the Asset Library.
Draw the control on the artboard with your pointer, or double-click the control in the Toolbox to insert the control at its default size.
If the control is one of the special types of text controls, Expression Blend enters text-editing mode and positions your cursor at the start of the text. You can exit text-editing mode by pressing ESC, and you can re-enter text-editing mode by pressing F2.
