Hidden Tools
When you open PSE you can see on the left side of your screen a column where all your tools are located.
Not only do you do have the tools you see but you also have tools that are hidden. All of the tools that have an arrow in the bottom right corner have more tools hiding in there. To find them, hover your pointer over the tool and then hold down your RIGHT CLICKER. The hidden tools will appear and you can just click on it to access.
