These tools are common in all photo editing applications. In Photoshop the tool panel is at the left of the Photoshop window. The tools in Photoshop we learnt this week are Painting tools, Selection tools, Navigation tools and Erasers.

The Selection tools include the Marquee tools, Lasso tools, Quick selection, you can select the tools by clicking on their icons/ symbols or  use key board shortcuts.

Marquee tools=======> Control(or Command) + M
Lasso tools =========>Control(or Command) + L
The move tool=======>Control(or Command) + V
Quick Selection======>Control(or Command) + W

A Marque tool can be used (that is if you have selected one) by pointing your mouse over desired area and draging out upto the desired size. The tool can be rectangular. elliptical, single column (vertical line) or single row (horizontal).
The Lasso tools will help you select irregular shapes they include the lasso, polygonal and magnetic lasso tools. The lasso tool is used by clicking and dragging around the irregular shape or any kind of shape. The polygonal tools lets you create anchors while selecting around the shape/image then the magnetic tool sort of works like the polygonal tool expect it helps you automatically create anchoring points around the shape by checking difference in color pixels.
Quick Selection and Magic wand tools are used for quick selection. The magic wand selects all areas of the image with the same color as that of the area you clicked on.
The move tool can be used to move the selection or the selected area.

The tools can do more than mentioned above by using the option bar that comes up as soon as you select one of the tools. The bar includes Adding, selecting and intersecting options. This helps to add or subtract from a shape to create a new one. This option can also let you use more than one type of selection tool.
