There is no single keyboard shortcut that works in every operating system and application. The actions are often shared; the keys usually are not. Windows, Linux and ChromeOS commonly use Ctrl for everyday commands, while macOS usually uses Command. Use the guide below as a practical starting point, then check the active app when a shortcut behaves differently.
Quick reference: common shortcuts
These are widely supported conventions, not guarantees. The result depends on the app and what currently has keyboard focus.
| Action | Windows, Linux, ChromeOS | macOS |
|---|---|---|
| Copy | Ctrl+C | Command+C |
| Cut | Ctrl+X | Command+X |
| Paste | Ctrl+V | Command+V |
| Undo | Ctrl+Z | Command+Z |
| Redo | Ctrl+Shift+Z or, in some apps, Ctrl+Y | Command+Shift+Z in many apps |
| Select all | Ctrl+A | Command+A |
| Find in the current view | Ctrl+F | Command+F |
| Save | Ctrl+S | Command+S |
| Open | Ctrl+O | Command+O |
| Ctrl+P | Command+P | |
| New document or window | Ctrl+N | Command+N |
| Close the current tab or window | Ctrl+W | Command+W |
On Windows and Linux, Ctrl+C is not the general macOS equivalent: use Command+C in most Mac apps. ChromeOS follows many of the same Ctrl-based editing conventions as Windows and Linux. Google’s Chromebook shortcut reference and Chrome shortcut reference list platform-specific combinations rather than claiming one set fits all.

A shortcut can be universal in function without using identical keys everywhere. Copy, paste, undo, select all and find are common actions across major systems and applications. Their familiar combinations are conventions, not a single standard that every developer must implement.

- Application shortcuts: commands for a browser, spreadsheet, code editor or creative app. They may differ even between versions of the same application on different platforms.
Even a familiar shortcut may do nothing, have another meaning or be captured by the operating system. The application menu is often the quickest way to confirm the command and its current key binding.
Core shortcuts and their limits
Clipboard, undo and selection
Copy, cut and paste work in most editable contexts, but the application controls what can be selected and what gets pasted. A destination may discard formatting, convert it or block pasting. Ctrl+Shift+V often means paste without formatting on Windows, Linux and ChromeOS; on macOS, a similar command in Apple apps is often Option+Shift+Command+V. Neither combination is dependable in every app, so check its Edit menu or shortcut settings.
Undo usually follows the Ctrl+Z/Command+Z pattern. Redo is less consistent: many Windows and Linux apps use Ctrl+Shift+Z, while others use Ctrl+Y. On Mac, Command+Shift+Z is common. When the action matters, use the app’s menu to verify.
Ctrl+A or Command+A selects all within the active context, not necessarily the whole application. In a text field it may select that field’s text; in a document it may select the document contents.

Find, save, open and print
Ctrl+F or Command+F usually searches the current page, document or application view. Ctrl+S or Command+S commonly saves, but a web app with automatic saving may show no visible change. Ctrl+O/Command+O generally opens a file or document picker, and Ctrl+P/Command+P generally opens a print dialog when the app supports printing.
Ctrl+N/Command+N can mean a new document or a new window, depending on the app. Likewise, Ctrl+W/Command+W usually closes the current tab or window, but it is not a universal “quit application” command. Save important work before closing; behavior depends on the application and its unsaved-work prompts.
Text navigation: useful, but less consistent
Arrow keys move by character or line in many text controls. For word-level editing, common conventions are Ctrl+Left/Ctrl+Right on Windows and Linux, and Option+Left/Option+Right in many macOS text fields. Add Shift to extend the selection in many apps.
- Select a word at a time: commonly Ctrl+Shift+Left/Right on Windows/Linux or Option+Shift+Left/Right on macOS.
- Delete the previous word: commonly Ctrl+Backspace on Windows, Linux and ChromeOS; often Option+Delete on Mac keyboards.
- Beginning or end of line: Home and End are common on Windows/Linux, but Mac apps and compact keyboards may use Command+Left/Right or Fn combinations.
These are conventions, not guarantees. Terminals, editors, browser fields and remote sessions may interpret the same key sequence differently.

Browser shortcuts (Chrome examples)
Browser shortcuts are not operating-system-wide shortcuts. The combinations below are Chrome conventions; browsers can differ, particularly on macOS. Consult the official Chrome shortcut list for the current set.
| Action | Windows, Linux, ChromeOS | macOS |
|---|---|---|
| New tab | Ctrl+T | Command+T |
| Reopen closed tab | Ctrl+Shift+T | Command+Shift+T |
| Close tab | Ctrl+W | Command+W |
| Next tab | Ctrl+Tab or Ctrl+Page Down | Command+Option+Right Arrow |
| Previous tab | Ctrl+Shift+Tab or Ctrl+Page Up | Command+Option+Left Arrow |
| Go to tab 1–8 | Ctrl+1 through Ctrl+8 | Command+1 through Command+8 |
| Go to last tab | Ctrl+9 | Command+9 |
| Find on page | Ctrl+F | Command+F |
| Reload | Ctrl+R | Command+R |
| Focus address bar | Ctrl+L or Alt+D | Command+L |
| Zoom in / out / reset | Ctrl++ / Ctrl+- / Ctrl+0 | Command++ / Command+- / Command+0 |
Some browsers or extensions capture a shortcut, and browser versions can change details. For instance, do not assume a hard-reload combination shown for one platform will be identical on another.
How the platforms differ
Windows
Windows-specific shortcuts are useful but are not part of the common application layer. High-value examples include Windows+D to show or hide the desktop, Windows+E for File Explorer, Windows+L to lock the PC, Windows+R for Run, Windows+I for Settings, Alt+Tab to switch windows, Alt+F4 to close the active window, and Ctrl+Shift+Esc to open Task Manager. Windows+V opens clipboard history if enabled; Windows+Shift+S starts a screen snip. The Windows key plus arrow keys can arrange windows, subject to Windows version and configuration.

macOS
Command is the primary modifier for many application commands. Option often changes text movement, deletion or command behavior; Control has distinct system and contextual uses; and Fn may be needed on compact keyboards for function-row or navigation keys. Mac keyboards label the forward-delete key as Delete; on many compact models, Fn+Delete performs forward delete. These modifiers are not interchangeable with Windows keys in every context. App versions on Mac may also have different shortcuts from their Windows versions.

Linux
There is no single Linux desktop shortcut set. GNOME, KDE Plasma, Xfce and other desktop environments supply different system and window-management bindings; window managers such as i3 or Sway may be configured differently again. Many Linux applications use familiar Ctrl-based editing shortcuts, and browsers bring their own conventions. In a terminal, Ctrl+C commonly interrupts a running process rather than copying selected text. Distinguish desktop shortcuts, terminal-emulator shortcuts and shell behavior.
ChromeOS
Chromebooks share many Ctrl-based editing commands with Windows and Linux, but system shortcuts often use the Search or Launcher key. For example, Search+L locks the screen. Ctrl+Show Windows captures the screen, and Shift+Ctrl+Show Windows captures a selected area. A Windows keyboard connected to a Chromebook can use its Windows key as the Search/Launcher key in many shortcuts.

Keyboard commands can be an essential way to navigate without a mouse, magnify the screen, use speech input or operate assistive features. Windows examples documented for Windows 10 and 11 include:

- Shift pressed five times to toggle Sticky Keys; Left Alt+Left Shift+Num Lock to toggle Mouse Keys.
ChromeOS includes shortcuts for ChromeVox, screen magnification, high contrast and keyboard navigation; use the Chromebook shortcut reference for the device’s exact combinations. Screen-reader commands in particular can be captured by the assistive technology rather than the app. Check current documentation before relying on an unfamiliar accessibility toggle.
Why a shortcut may not work
- The app has its own binding. A command can vary by app, mode or platform. In a terminal, Ctrl+C may interrupt a process instead of copying.
- Focus is elsewhere. The cursor may be in the address bar, a password field, a dialog, a spreadsheet cell editor or a remote desktop rather than the document you meant to control.
- The keyboard layout differs. Shortcuts involving punctuation or symbols can require different physical keys on non-US layouts. Some official Chromebook guidance is based on standard English QWERTY layouts.
- The key is missing or has a secondary function. Compact keyboards may hide navigation or function keys behind Fn; laptops may treat the top row as media controls.
- A browser, extension or web app captures it. Web apps may intercept commands such as save, print, find or close-tab shortcuts.
- A remote session receives a different key. The local system may handle a combination before it reaches the remote machine. Microsoft notes that Mac shortcuts may not behave as expected in Windows remote sessions; see its keyboard guidance for Windows App.
- The system reserves it. Some combinations cannot be reassigned by an app or remapping utility. Microsoft documents, for example, that PowerToys Keyboard Manager cannot remap Windows+L or Ctrl+Alt+Delete.
- Two remapping layers conflict. Keyboard firmware, operating-system tools, macros and app settings can each transform or intercept a key.
Make shortcuts more consistent across devices
Start with native shortcuts. They are easier to use on someone else’s computer and simpler to troubleshoot. Remapping can be worthwhile if you switch platforms often, need a more comfortable combination, use an unfamiliar keyboard, or want an accessibility accommodation. It does not make a shortcut portable to computers where the remap is absent.
Recommended Free Tools
| Option | Best fit | Limit to know |
|---|---|---|
| Microsoft PowerToys Keyboard Manager | Windows users remapping keys or combinations, including app-specific mappings | PowerToys must be running; reserved combinations and usually Fn cannot be remapped. See Microsoft’s documentation. |
| Karabiner-Elements | Mac users needing modifier swaps, complex rules or deeper keyboard customization | It is a macOS tool, not a cross-platform solution. The project says it is free to use and accepts donations; see the official site and pricing information. |
| ChromeOS Shortcuts app | Chromebook users looking up or changing supported bindings | Some bindings are locked or unavailable, and browser conflicts constrain choices. See Google’s customization guide. |
| Keyboard firmware or onboard profiles | People who need a mapping to travel with compatible hardware | Features vary by keyboard; firmware mappings can conflict with software remappers and may not be app-aware. |
Remapping may be unavailable at login screens, secure prompts or before the operating system starts. It can also complicate workplace support: another user or administrator may not know your custom binding. Avoid replacing a heavily used or system-reserved shortcut unless you have tested a reliable fallback.
Troubleshoot a shortcut in order
- Confirm the active application and exactly which field or window has focus.
- Try the action in a basic text editor to see whether the issue is app-specific.
- Check the operating system, app version and keyboard layout.
- Confirm the required key exists and whether it needs Fn or function-key mode.
- Try the platform equivalent, such as Command instead of Ctrl on macOS.
- Check the app’s menus or shortcut settings for the current binding.
- Look for browser extensions, macros, assistive software or another remapper capturing the keys.
- Test outside a remote desktop or virtual machine if one is involved.
- Temporarily disable custom remaps, then test again.
- Restore the app or system’s default binding if a custom setting caused the problem.
- Use the application menu as the fallback and note its displayed shortcut.
- If you remap the command, choose a combination that avoids common system and app shortcuts, then test it in every context you use.
For Windows shortcut conventions, see Microsoft’s Windows keyboard tips. For system-specific or professional applications, an official app shortcut reference is more reliable than a general cross-platform list.
