Load selection.

This is how to use the load selection tool. There are different ways you can do it the easiest way to select a difficult shape or custom text is to press CTRL and click on the layer icon and it selects all the lines on that layer.

Another way is to use the rectangle marquee tool which makes a rectangle shape around the area you want.

You can also use the lasso tool to select around the area free handed by using a mouse or tablet.

I also found this easy to use because I have used it so many times in Graphics and at home.
