I can statements:

What is the TOOLBAR?
The Toolbar (also known as the Toolbox or the Tools panel) is where Photoshop holds all of its tools. You'll find it along the left of Photoshop's interface. There's tools for making selections, for editing and retouching images, for painting, adding type or shapes to your document, and more:
By default, the Toolbar appears as a long, single column of tools. Clicking the double-arrows at the top will EXPAND YOUR TOOLBAR into a shorter, double column. Click the arrows again to return to the single-column layout:
The Toolbar's Hidden Tools
Photoshop includes lots of tools. In fact, there are many more tools than what we see. Most of the tools in the Toolbar have other tools nested in with them in the same spot. Click and hold on a tool's icon to view a menu of the other tools hiding behind it.
For example, by default, the Rectangular Marquee Tool is selected. It's the second tool from the top. If I click and hold on the Rectangular Marquee Tool's icon, a fly-out menu appears. The menu shows me that the Elliptical Marquee Tool, the Single Row Marquee Tool and the Single Column Marquee Tool can also be selected from that same spot. We'll learn more about the Toolbar in the next tutorial, and we'll learn how to use Photoshop's tools in other lessons throughout this training series:
Most of the spots in the Toolbar hold several tools, not just one.
