Photoshop Tips 
1,  2,  3,  4,  5,  6,  7,  8,  9, 10

  Being a visual person myself, I actually enjoy hunting for those little Icons in
Photoshop.  But as a friend showed  me, knowing a few keyboard shortcuts can
and does save a lot of time.  Personally, I am a PC man; but for those of you on
MAC you can just substitute the Command key for the Control key and achieve
the same results.

          Ctrl+A . . . . . Select All               
        Ctrl+C . . . . . Copy
        Ctrl+D . . . . . Deselect
        Ctrl+E . . . . . Merge Selected Layers
        Ctrl+G . . . . . Group items together
        Ctrl+H . . . . . Hide/Show Selected Items
        Ctrl+S . . . . . Save (use often)
        Ctrl+U . . . . . Adjust Hue/Saturation
        Ctrl+V . . . . . Pastes a copy in the center of a new layer
        Ctrl+X . . . . . Cut (pastes the item to your computer's clipboard)
        Ctrl+Z . . . . . Undo the last action
        Shift+Ctrl+I . . . . . Inverse the selection
        Shift+Ctrl+N . . . . . Create New Layer

Here's a list of most of the tools from the toolbar. Keep in mind this is from Photoshop 7.0, but all of these "plus more" should be available in the newer versions. These tools all have a single letter that you type to access that tool. For tools that are grouped together, they share a keystroke that you would type more than once to access the second or third tool in a group. For example,  type "m" to bring up the Rectangular Marquee Tool, but type "mm" to get to the Elliptical Marquee Tool.
