Handy for finding the perfect font because it makes the process totally visual. Highlight your type (mini-tip: double-click directly on the "T" thumbnail in the Layers panel to instantly select all the type on that layer), then take your cursor and click once directly inside the Font field up in Photoshop's Options Bar (as seen below). Now just use the Up/Down arrow keys on your keyboard to see your type change live as you move through your font list. When you see the one that looks good to you, you're set!
Tip 6 - Create a Stamp Visible
Sometimes you need to merge all the layers in the document to a single new layer but you want to maintain all the work done below it intact. To do that, click the top layer and hit Ctrl + Shift + Alt + E (Command + Option + Shift + E on the Mac).
Tip 7 - Filling a layer with the foreground or background color
To fill a layer or a selection with the foreground color hit Alt + Backspace (Option + Delete on the Mac).

Tip 8 - Reduce layer opacity with a slider

Tip 9 - Copy layer style the quick and dirty way!

Tip 10 - Select a layer automatically from the canvas
If you are not used to select the desired layer from the layers panel, you’ll love this tip.
You have to be on the Move Tool to see a checkbox in the control panel (below the main menu). called Auto Select. Turn this option on and you will be able to click anywhere in your canvas to automatically select the layer underneath your cursor. This setting is especially handy if you are working with text or photo collage.
Tip 11 - Select a layer from another layer (sounds confusing!)
This tip is handy when you have too many layers on top of each others in your document. Make sure the Move Tool is the active tool. Hover over the area of your document that has the desired layer. Right-click to trigger a context sensitive menu showing you all the layers underneath your cursor. Select the desired layer.
Tip 12 - Use layer masks to quickly hide the background
Imagine you have a picture of a dog you want to change the cluttery background of and you want to cut out only the dog for that matter. Start by using the Magic Wand tool to select the background. Normally by pressing the Delete key we would delete the background but we want a less destructive way instead. So we will use Layer Masks.
Now, hit the ctrl + shift + I (cmd + shift + I on the Mac) to invert the selection. With the dog now selected, add a mask using the Add Mask button. Photoshop will automatically hide what is not selected. Remember: black hides and white reveals.
