 Useful Tips

1. Moving Layers with the Control Key

You don't need to activate the Move Tool to move layers around. Simply hold down the Control key (for Windows users) or the Command key (Mac users) and click and drag on your layer with the mouse:

2. Selecting All Pixels on a Layer

To select all the opaque pixels on a layer (as opposed to using Select All, which selects the whole layer), hold down the Control key (Windows) or Command key (Mac), and click on the layer in the Layers Palette

3. Hiding the Palettes with the Tab Key

Are the palettes getting in the way? You can hide them temporarily just by hitting the Tab key. To bring them back, press the Tab key again.

4. Use Layer Sets

If you're using Photoshop 6, check out Layer Sets. These let you organize your layers into folders - very useful if you have lots of layers in a document! To create a new Layer Set, click on the folder icon at the bottom of the Layers Palette, then drag layers on top of a layer set to add them to the set

5. Double-Click to Open Documents

To open a document in Photoshop, you don't need to reach for the File > Open menu option or even press Control+O - you can just double-click on the grey Photoshop window background!

6. Dragging Layers Between Documents

You can copy a layer from one document to another by clicking on it in the Layers Palette and dragging it across to the second document window

7. Keeping to Straight Lines

You can often constrain movement of the mouse to the nearest 45-degree or 90-degree angle by holding down the Shift key while you click and drag with the mouse. This works on tools such as the Paintbrush Tool, Line Tool and Move Tool. Great for drawing straight lines!
