Well there is another way to it. You don't have to always make such simple shapes all the time.Some shapes and graphics are already given in PSE 11. Those are very handy and always ready to use.
Just switch to Expert mode, in the bottom right side you will see Graphics. Click on it, a panel will appear. In the dropdown list choose Graphics/Shapes.
A whole list is available for you, with various options to choose.
I found it; however, I noticed there are two dropdown lists above the Graphics panel. The one on the right with the top list item "Backgrounds" is the one containing the shapes.
Thanks for your help.
