When
you use the Horizontal Type Mask tool or Vertical Type Mask tool,
you create a selection in the shape of the type. Type selections
appear on the active layer, and can be moved, copied, filled, or
stroked just like any other selection.
Select the layer on which you want the selection
to appear. For best results, create the type selection border on
a normal image layer, not a type layer. If you want to fill or stroke
the type selection border, create it on a new blank layer.
Select the Horizontal Type Mask tool or
the Vertical Type Mask tool .
Select additional type options, and enter type at a point
or in a bounding box.
A red mask appears over the active layer as you enter the
type. After you click the Commit button , the
type selection border appears in the image on the active layer.
