Holding the Option (Mac) / Alt (Win) key while dragging the Lasso tool will toggle to the Polygonal Lasso tool and vice versa. When starting with the Lasso tool, this previous shortcut might take a few tries to master as you have to be careful to release the Option key (to return from the Polygonal Lasso tool to the regular Lasso) while holding the mouse down.
In addition, holding the Option (Mac) / Alt (Win) key while dragging the Magnetic Lasso will toggle to the regular Lasso if you drag with the cursor and the Polygonal Lasso if you click with the cursor.

To auto select a layer, with the Move tool selected, check the Auto-Selection option in the Options bar. Choose between Auto-Select Layers or Group. Or, to temporarily invoke the Auto-Select functionality, with the Move tool selected, Command (Mac) / Control (Win) -click on part of the layer’s content. To select more than one layer, Shift-click on the layer’s content in the image area. Shift clicking on an already selected object deselects it.
With the Auto-Select feature invoked, you can also click-drag over objects in the image area, to select their corresponding layers in the Layers panel. This method works well if you have multiple objects (layers) and a Background. Otherwise, because you have the Auto Select feature turned on, clicking in the image area will auto-select the first layer that you click on and begin to move it instead of selecting additional objects (layers). Because a Background is locked by default, it is impossible to select and therefore skipped by the Auto Select Feature. Hint: if you have layers that you do not want to auto select, lock them.

After making complex selections, it is possible to save them for use again later but choosing Select / Save Selection. This saves the selection as an alpha channel. Alpha Channels can be saved in several file formats including Photoshop and TIFF (they can not be saved as part of a JPEG file however).

The Marquee, Lasso, Magic Wand and Quick Selection tools all share some common shortcuts that can help you when making more complex selections (Instead of using the icons in the Options bar):
• Holding the Shift key and dragging with the tool will add to an existing selection.
• Holding the Option (Mac) / Alt (Win) and dragging with the tool will subtract from the original selection.
• Holding the Option (Mac) / Alt (Win) + Shift and dragging with the tool will produce the intersection of selections.
• After creating a selection, you can move a it by 1 pixel with the arrow keys. Add the Shift key to move in increments of 10 pixels.
• Holding the Shift key after beginning to move a selection or layer will constrain the movement to multiples of 45° (0°, 45°, 90° etc.).
