What is the default Undo shortcut in Photoshop on Windows?
Ctrl+Z
Alt+Z
Ctrl+Y
Ctrl+Shift+Z
On Windows, Photoshop uses Ctrl+Z as the toggling Undo/Redo shortcut for the last change. Earlier versions stepped back only one history state, but current Photoshop toggles between Undo and Redo with Ctrl+Z by default. To step through multiple history states you use Ctrl+Alt+Z. For more details, see Adobe Help on History and Undo.
What is the default Undo shortcut in Photoshop on macOS?
Command+Z
Option+Z
Command+Y
Command+Shift+Z
On macOS, Photoshop uses Command+Z to toggle Undo and Redo on the last step, mirroring the Windows Ctrl+Z behavior. To step backward through multiple states you use Command+Option+Z instead. This toggle behavior was updated in Creative Cloud versions. For full details, see Adobe Help on History and Undo.
Which shortcut allows stepping backward through multiple history states on Windows?
Ctrl+Alt+Z
Ctrl+Shift+Z
Ctrl+Z
Ctrl+Y
Ctrl+Alt+Z on Windows is the classic multi-step Undo shortcut, moving you backward through the History panel states beyond the last action. This differs from Ctrl+Z, which toggles between the last state and the current one. For more information on stepwise Undo, refer to Adobe Help on History and Undo.
Which shortcut allows stepping backward through multiple history states on macOS?
Command+Option+Z
Command+Shift+Option+Z
Command+Option+Y
Command+Shift+Z
Command+Option+Z on macOS undoes multiple steps in Photoshop’s History panel, moving you backward through your editing history. This is analogous to the Windows Ctrl+Alt+Z shortcut. Photoshop CC uses Command+Z to toggle Undo/Redo of the last command. See Adobe Help on History and Undo for more.
How do you step forward after stepping backward through history states on Windows?
Ctrl+Shift+Z
Ctrl+Y
Ctrl+Alt+Z
Ctrl+Z
After using Ctrl+Alt+Z to step backward, Ctrl+Shift+Z on Windows will step forward through History states. Ctrl+Z only toggles the last action, while Ctrl+Shift+Z advances you in the history list. You can confirm or adjust History preferences in the Performance section. For reference, see Adobe Help on History and Undo.
How do you step forward after stepping backward through history states on macOS?
Command+Shift+Z
Command+Y
Command+Option+Z
Command+Z
On macOS, once you’ve stepped backward with Command+Option+Z, you use Command+Shift+Z to step forward through history states. Command+Z simply toggles the last change. This multi-step behavior allows precise navigation of your editing history. See Adobe Help on History and Undo.
Which menu path contains the Undo command?
Edit > Undo
File > Undo
View > Undo
Layer > Undo
Photoshop’s Undo command is located under the Edit menu. The menu item reads Undo [Last Command], changing dynamically to Redo if you have already undone. This is a fundamental location for basic command reversal. For more, see Adobe Help on History and Undo.
Which panel displays a list of recent states you can revert to?
History panel
Layers panel
Actions panel
Properties panel
The History panel in Photoshop lists each state you’ve created during your session, allowing you to click back to any recorded step. Layers and Actions panels serve different purposes. To show the History panel, go to Window > History. Learn more at Adobe Help on History and Undo.
How many history states are saved by default in Photoshop’s Preferences?
50
20
30
100
By default, Photoshop retains 50 history states, meaning you can undo up to fifty steps in your session. You can increase or decrease this number in Preferences to trade off between undo depth and memory usage. See Adobe Help on Performance Preferences.
In Preferences, which section allows you to change the number of history states?
Performance
General
Interface
File Handling
You adjust the number of history states in Edit > Preferences > Performance (Windows) or Photoshop > Preferences > Performance (macOS). This section also controls memory allocation and GPU settings. Tweaking these can help Photoshop run more smoothly with deep history. Read more at Adobe Help on Performance Preferences.
Which key, when held while dragging a layer, duplicates the layer?
Alt
Ctrl
Shift
Tab
Holding Alt (Windows) or Option (macOS) while dragging a layer in the canvas or Layers panel duplicates it. This is a quick way to copy layers without using keyboard commands. It’s covered in Adobe’s layer management guide. See Adobe Help on Layer Management.
What is the shortcut to group selected layers?
Ctrl+G
Ctrl+Shift+G
Ctrl+Alt+G
Ctrl+H
Ctrl+G (Windows) or Command+G (macOS) groups selected layers into a folder. Ungrouping uses Ctrl+Shift+G. Layer groups help organize complex documents. For more, see Adobe Help on Organizing Layers.
What is the keyboard shortcut to create a new blank layer above the active layer?
Ctrl+Shift+N
Ctrl+Alt+N
Shift+N
N
Ctrl+Shift+N opens the New Layer dialog, letting you name and style the new layer before creation. This is faster than going through the Layer menu. For more, see Adobe Help on Layers.
Which key resets the foreground and background colors to black and white?

What is the shortcut to enter Free Transform mode?
Ctrl+T
Ctrl+R
Ctrl+F
Ctrl+M
Ctrl+T (Windows) or Command+T (macOS) activates Free Transform, letting you scale, rotate, skew, and distort a layer or selection. You can constrain proportions by holding Shift (unless preferences are updated). For details, see Adobe Help on Transforming Objects.
Which key temporarily switches to the Hand tool?
Spacebar

Holding the Spacebar temporarily activates the Hand tool, allowing you to pan around the canvas without changing tools permanently. Releasing Spacebar returns you to your previous tool. This is essential for navigation in large documents. See Adobe Help on Pan and Zoom.
Which key hides or shows all panels?
Tab
T
Ctrl+H
F

1000
500
100

Which shortcut merges all visible layers into a new layer without flattening?
Ctrl+Shift+Alt+E
Ctrl+E
Ctrl+Alt+E
Ctrl+Shift+E

Use Legacy Undo Shortcuts
Enable Linear Undo
Legacy History Mode
Use Non-Linear Undo
Photoshop CC introduced a toggle Undo that alternates between Undo and Redo with the same shortcut.

Cheat Sheet

  1. Master the Photoshop Undo Hotkey Variants -

    Adobe Help Center explains that the photoshop undo hotkey (Ctrl+Z on Windows or Cmd+Z on Mac) toggles between your last two states, while multiple undos use Ctrl+Alt+Z/Cmd+Option+Z to step backward through history. Think "Z" for zero mistakes - tapping Z is like saying "undo one," and Alt/Option extends your steps.

  2. Customize Keyboard Shortcuts for Speed -

    In Photoshop's Edit > Keyboard Shortcuts menu you can assign or change any hotkey, including the photoshop undo hotkey and other adobe photoshop shortcuts. Try remapping "Step Backward" (Edit > Step Backward) to a single key combo you find ergonomic; using two-finger patterns can shave seconds off each edit. University design labs often recommend customizing keys to avoid menu dives and keep your focus on the canvas.

  3. Leverage the History Panel and Snapshots -

    The History panel (Window > History) offers a visual roadmap of all your recent edits, letting you revert multiple steps with a single click rather than repeatedly tapping the photoshop undo hotkey. Create snapshots at key milestones (by clicking the camera icon) so you can jump back to a clean state instantly. This technique is endorsed by Adobe's official documentation for non-linear workflows.

  4. Use the History Brush for Selective Undos -

    The History Brush (Y) lets you paint back pixels from past states, acting like a "local undo" instead of a global rollback via the photoshop undo hotkey. Select a history state in the History panel, then brush over areas you want to restore - perfect for correcting small mistakes without losing subsequent edits. Industry tutorials, such as those on Adobe Training, recommend this for detailed retouching.

  5. Practice with Mnemonics and Spaced Repetition -

    Reinforce photoshop keyboard shortcuts by using mnemonic phrases like "Undo Zeros Mistakes" or flashcard apps that quiz you on adobe photoshop shortcuts daily. Research on skill retention from academic sources (e.g., Journal of Educational Psychology) shows that spaced repetition dramatically improves recall and typing speed. Turn your cheat-sheet into an Anki deck and review it before each design session for rapid mastery.
