Using text
The Text icon is that capital T in the lower half of the Tools Window, and right-clicking it enables you to change the orientation. The Properties bar at the top of the screen gives you size, shape, justification and font options so you can customise your text. Any fonts installed on your computer are accessible in Photoshop, although having too many can slow down the program (which is also a downside to having too many brushes). Text can be altered with the Free Transform process mentioned previously (right-click the layer and rasterize it first) and clicking the warped T over a curved line (in the Properties bar once again) will open up some useful preset warping options.
