Essential Photoshop Shortcut Commands

• F (Cycle Screen Modes) — Switch between
  normal screen, full screen with task bar without title bar, and full
  screen with black background. Works great when used in conjunction with
  Tab to hide toolbars — maximum working space, no distractions.
• X (Switch Colors) — Swap your foreground and background colors. Very handy when working with masks.
• D (Default Colors) — Reset your foreground and background colors to black and white, respectively.
• Ctrl + ‘+’/’-’ (Zoom In/Out) — Quickly zoom in or out without changing your current tool.
• Alt + Mouse Scroll (Zoom In/Out) — Fastest way to zoom — scroll up to zoom in, and scroll down to zoom out.
• Ctrl + Alt + Z (Step Back) — Ctrl + Z is OK if you catch a mistake immediately after it happens, but this command will continue to march its way up the history tree.
• Ctrl + S (Save) — You should get in the habit of just hitting this combo on impulse about every 5 to 10 minutes. Also use Ctrl + Alt + Shift + S to bring up the save for web dialog.
• Ctrl + Alt + Shift + N (New Layer No Dialog) — Quickly insert a new empty layer on top of the active layer. Get rid of the Alt key to bring up the new layer dialog for more options.

Useful Photoshop Shortcut Commands

• Shift + Click Mask (Enable/Disable Layer Mask)
  — When working with masks it’s typically done in small
  increments. Disabling the mask allows you to check the results of your
  masking against the original.
• Alt + Click Mask (Toggle Mask Visibility) —
  Doing this will bring up the mask as a grayscale image so you can see
  what you’re working with. Useful if you have areas that need to
  be filled in or smoothed out.
• Ctrl + Click Mask (Load Mask As Selection) —
  Selects the white part of the mask (grays are partially selected).
  Useful if you want to duplicate a mask or it’s inverse. Using Ctrl + Click on a layer without a mask will select the non-transparent pixels in that layer.
• Ctrl + J (New Layer Via Copy) — Can be used
  to duplicate the active layer into a new layer. If a selection is made,
  this command will only copy the selected area into the new layer.
• Caps Lock (Toggle Cross Hairs) — Switch
  between the standard tool icon and a set of precision cross hairs.
  Useful for spot-on selections.
• Shift + Backspace (Fill Dialog) — Good time saver when working with masks. Also, use the Ctrl + Backspace to fill with background color and Alt + Backspace to fill with foreground color.
• Ctrl + H (Hide Selection Lines) — When
  working with selections, use this command to hide the “marching
  ants” while keeping the selection.
• Ctrl + I (Invert Selection) — Select the opposite of what is already selected. Also a good tool when working with mask creation.
• Ctrl + D (Deselect) — After working with your selection, use this combo to discard it.
• Side Note: When working with selections, they can
  be applied to a layer as a mask simply by adding a new layer mask using
  the little box-with-a-circle-inside icon at the bottom of the layer
  palette. This also works with adjustment layers by automatically
  applying the selection to the mask.

Handy Photoshop Shortcut Commands

• Ctrl + G (Group Layers) — This command groups selected layers in the layer tree. Adding Shift to this combo will ungroup layers when the grouped layer is selected.
• Ctrl + A (Select All) — Creates a selection around the entire canvas.
• Ctrl + T (Free Transform) — Brings up the
  free transform tool for resizing, rotating, and skewing the image using
  a dragable outline.
• Ctrl + E (Merge Layers) — Merges selected
  layer with the layer directly below it. If multiple layers are
  selected, only those will be merged.
• Crtl + Shift + E (Merge Visible) — Merges
  all visible layers into one. Not recommended practice in typical photo
  editing because you’ll lose layer information.
• Ctrl + Alt + E (Stamp Down) — Merges all selected layers into one new layer. Add the Shift
  modifier to this combo and you’ll get a new layer containing a
  merged representation of all visible layers (handy for sharpening
  adjustments)
• Ctrl + Alt + Shift + R (Rotate Arbitrary Dialog)
  — bring up the rotate dialog to straighten out your
  horizon… but it’s not typically used since we all take
  perfect photos, right?
• Side Note: Adobe Camera Raw (ACR) has the ability
  to straighten photos before they ever make it into Photoshop. When
  straightening, you draw a line you’d like as your horizontal and
  ACR will take care of the rotation and crop for you.
• CTRL + ALT + DEL (Kill Photoshop) — Quite useful when Photoshop takes your computer hostage. Must have used the Ctrl + S command prior to the hostile takeover in order to prevent mental breakdown.
