Adobe 65016169 - Photoshop CS4 Extended Tutorial page 10

If you used other Adobe products, such as Illustrator or InDesign, you should be familiar with the
toolbox in Adobe Photoshop CS4 as it shares some of the tools from these applications. If you are
a novice user of Adobe products, you should keep in mind that you might not need to use all of the
tools. In this tutorial, only the basic tools will be discussed in depth.
Some tools in the toolbar have additional "hidden" tools. These tools have small black triangles in
the right-hand corner. To view the "hidden" tools, click and hold down on any tool that has a black
triangle in the corner (Fig. 1).
