Handy GIMP shortcuts

I use the GIMP for my work, and I've found that these are the keyboard shortcuts that I use the most. Use them as combos! Try adding ctrl and shift to more tools and see what you get!

Start-up Stuff:

• Ctrl+1 (,2,3,4,5) = Open the first document in document history (the most recent document you worked on) –or the second-most recent, or the third, and so on up to 9.
• Ctrl+O = Open
• Ctrl+S = Save
• Ctrl+Shift+S = Save as... (aka “Save a copy”)
• Ctrl+D = Duplicate the current image into a new file
• Ctrl+E = Export
• Ctrl+Shift+E = Export to a different file name
• Ctrl+N = New document
• Ctrl+Shift+N = New Layer

Tools:

• N = Pencil
• P = Paintbrush
• X = Switch BG and FG colors
• O = eyedropper (color-picker)
• Ctrl while using pencil or paintbrush = eyedropper
• Shift+E = Eraser
• Shift+B = Fill Bucket
• [ = Shrink brush size
• ] = Increase brush size

Manipulation:

• Ctrl+C = Copy
• Ctrl+X = Cut
• Ctrl+V= Paste (but then you have to Anchor it—by mouse-click or by the button underneath the layers)
• Page Up = Move up a layer
• Page Down = Move down a layer

Selections:

• Ctrl+A = Select all 
• R = Rectangle (and E = Ellipse but I rarely use it)
• U = Magic Wand (select a contiguous section)
• Shift+O = Select by color (VERY handy!)
• F = Free-hand select (lasso)
• While using ANY selection tool:
  • Shift = add to selection
  • Ctrl = subtract from selection
  • Ctrl+Shift = Intersect with current selection (in other words: “only select inside what is already selected”—helpful for fine-tuning selections by color, for example)
  • Ctrl+I = invert selection

View:

• + = Zoom in
• - = Zoom out
• Space Bar(+mouse move) = Move around the image
• 1 = 100% view
