Operations with Selected Areas
The old selection does not necessarily gets cancelled when you make a new one. In can be combined with the new one or interact with it in other ways. These interactions are called Logical Operations. They are determined as parameters of the chosen selection tool and can be found at the Options palette.
Addition of the selections.
To combine selections you can do one of the following:
1. Set the second combining mode option in the Options palette without fooling with hotkeys and make a new selection that will be combined with the old one.
2. Without paying attention to the Options palette, make a new selection keeping Shift button pressed.
If you keep Shift pressed using any selection tool in Photoshop, new selection will be added to previous selection.
Subtraction of selections.
The third option in the Options panel stands for subtracting the selection. It is similar to combining selections and the hotkey to press is Alt. If you keep Alt pressed using any selection tool in Photoshop, new selection will be subtracted from the previous selection.
Intersection of Selections.
To form new selection that is the result of an intersection of new and old selections made in Photoshop you need to select the last option in the Options palette. You can enable this mode in Options palette or use Shift+Alt hotkey.
Inverse Selection Command
This is one of the most useful commands and it is frequently applied when working in Photoshop. Inverting the selection simply deselects selected objects at the same time selecting everything else in the image. Inverse selection is useful when you want to leave some object untouched. You can select the object and then invert the selection and edit everything else but the object. You can perform this going to Select > Inverse or by pressing Ctrl+Shift+I hotkey.
