None of these shortcuts do anything a menu cannot, but a selection is usually one small step inside a much longer edit, and reaching for a menu each time breaks the flow. This Quick Tip covers building a selection from a layer thumbnail, adding and subtracting with Shift and Alt, repositioning mid-drag with the Space bar, Quick Mask previewing, inverting, hiding the marching ants, and copying to a new layer.

Essential Selection Shortcuts in Photoshop
This Quick Tip runs through a set of keyboard shortcuts for building, adjusting, and previewing selections in Photoshop, the kind of small time-savers that add up across a retouching session.
Creating a Selection Straight from a Layer
Holding CTRL on a PC or CMD on a Mac and clicking a layer’s thumbnail in the Layers panel turns everything on that layer into an active selection, based on its transparency, without needing to trace it manually with any selection tool.
Selecting Everything at Once
CTRL + A on a PC, or CMD + A on a Mac, selects the entire canvas in one keystroke, a fast starting point whenever the whole image needs to be included.
Adding to an Existing Selection
Holding SHIFT while drawing a new selection with any selection tool adds that new area to whatever is already selected, building up a more complex selection from several separate pieces.
Subtracting from a Selection
Holding ALT on a PC, or OPTN on a Mac, while drawing does the opposite, removing the new area from the existing selection, which is the fast way to trim an unwanted piece off a selection without starting over.
Repositioning a Selection Mid-Drag
While actively dragging out a new selection, holding the Space bar lets the selection be moved to a different spot on the canvas without changing its size, then releasing Space continues resizing it from the new position.
Viewing a Selection in Quick Mask
Pressing Q switches into Quick Mask mode, which overlays the current selection as a colored, semi-transparent mask directly on the image, making it much easier to see exactly where a selection’s edges fall than the standard marching-ants outline alone.
Pressing Q Again Returns to a Normal Selection
Quick Mask mode can also be painted on directly with a brush to refine the selection, and pressing Q a second time converts that painted mask back into a standard active selection.
Inverting a Selection
CTRL + SHIFT + I on a PC, or CMD + SHIFT + I on a Mac, inverts the current selection, swapping what’s selected and what isn’t, which is useful whenever it’s easier to select the opposite of the area actually needed.
Hiding the Marching Ants
CTRL + H on a PC, or CMD + H on a Mac, hides the marching-ants outline around an active selection without deselecting it, which makes it easier to judge how an edit actually looks without the animated dashed line distracting from the image.
The Selection Is Still Active
Hiding the marching ants only affects what’s visible on screen; the selection itself stays fully active underneath, so any tool or adjustment applied while the ants are hidden is still constrained to that selected area.
Copying a Selection to Its Own New Layer
CTRL + J on a PC, or CMD + J on a Mac, copies whatever is currently selected onto a brand new layer directly above the original, isolating that piece of the image so it can be edited, moved, or restyled independently.
Faster Than Copy and Paste
This single shortcut does the same job as copying the selection and pasting it as a new layer, but in one step, without leaving the original selection sitting on the clipboard.

Why These Shortcuts Are Worth Learning
None of these shortcuts do anything that isn’t already possible through a menu, but selections are usually one small step in a much longer editing process, and reaching for a menu every time interrupts that flow far more than a single keystroke does. Shift and Alt in particular turn any selection tool into three tools at once, adding or subtracting as needed without ever switching away from it.
Final Thoughts
Building fluency with a handful of selection shortcuts, adding and subtracting on the fly, previewing in Quick Mask, inverting, hiding the marching ants, and copying a selection straight to its own layer, saves real time across nearly every kind of Photoshop edit that starts with isolating part of an image.
