Alright, now that we have a better idea of the menus in Photoshop, it's time to give the Tools a deeper look.
Your tool palette usually floats to the left of your screen, but you can certainly move it to the right side or some other place if you wish.
The tools are structured in two levels; the one level you can see, the other one you can't. Notice the little arrow at the bottom left of some tool icons?
Click and hold on one of them with your mouse and you will see a different set of tools pop out.
These are usually variations of the tool icons that you can see.
If you are familiar with the shortcuts for the tools, you should know that you can cycle within a set by holding SHIFT and pressing a key for a particular tool.
For example, you can select the bucket tool by pressing G once, and by pressing SHIFT + G you can select the gradient tool.
