You can change most keyboard shortcuts through your operating system settings or individual applications

Keyboard shortcuts are combinations of keys that trigger a specific action — like Ctrl+C to copy or Cmd+Q to quit on Mac. Most shortcuts are set by default, but you can reassign them to match how you work. The method depends on whether you want to change a shortcut in your operating system itself, in a specific application, or in a browser.

The process is straightforward on all three major operating systems, though the location of the settings differs. Some applications make it easier than others, and a few programs lock their shortcuts so you cannot change them. If a shortcut you want is already taken by another action, you will need to free it up first.

Key Takeaways

  • Windows shortcuts are changed in Settings under Accessibility, while Mac shortcuts live in System Settings under Keyboard, and Linux varies by desktop environment.
  • Individual applications often have their own shortcut settings, usually found in Preferences or Settings within the application menu.
  • Browser shortcuts can be changed through extensions like Vimium or through the browser's built-in keyboard settings if available.
  • If a shortcut is already assigned to another action, you must remove or change that assignment before you can use it elsewhere.
  • Some applications do not allow shortcut customization, particularly system-level programs and certain professional software with locked configurations.

Changing shortcuts in Windows

Open Settings and go to Accessibility, then Keyboard. Scroll down to find "Edit keyboard shortcuts" or "Remap keys" depending on your Windows version. This section lets you reassign individual keys or key combinations to different actions. Click the plus button to add a new shortcut, then press the keys you want to use and select the action you want them to trigger.

For application-specific shortcuts in Windows, open the application and look for Preferences, Settings, or Options in the menu bar. Many programs like Visual Studio Code, Notepad++, and Adobe applications have dedicated shortcut customization panels. Search the menu for "keyboard" or "shortcuts" if you cannot find it immediately. Some applications store shortcuts in a configuration file you can edit directly, though this requires more technical knowledge.

Changing shortcuts on Mac

Go to System Settings, then Keyboard, then Keyboard Shortcuts. You will see categories on the left side: App Shortcuts, Function Keys, Modifier Keys, and others depending on your macOS version. Select the category that matches what you want to change. To create a new shortcut for an application, click the plus button, choose the application from the dropdown, type the menu item name exactly as it appears, then press the key combination you want to assign.

For application-specific shortcuts, open the application itself and look in the menu bar for Preferences or Settings. Many Mac applications like Sublime Text, Final Cut Pro, and Affinity apps have their own keyboard customization sections. If you want to change a modifier key itself — like making Caps Lock behave as Control — that is also in System Settings under Keyboard, in the Modifier Keys section.

Changing shortcuts on Linux

Linux shortcut customization depends on your desktop environment. On GNOME, go to Settings, then Keyboard, then View and Customize Shortcuts. On KDE Plasma, open System Settings, then Shortcuts. On other environments like XFCE or Cinnamon, look in Settings under Keyboard or Accessibility. The interface varies, but the principle is the same: find the action you want to reassign and click it to enter a new key combination.

For application-specific shortcuts on Linux, check the application's Preferences or Settings menu. Many open-source applications like GIMP, Blender, and Audacity have detailed keyboard customization options. Some applications store shortcuts in configuration files in your home directory — for example, many terminal-based tools use files like .config/application-name/keybindings — but editing these requires familiarity with text editors and file paths.

Changing shortcuts in web browsers

Most browsers do not allow you to change their built-in shortcuts directly through settings. However, you can use extensions to create custom shortcuts. Vimium (available for Chrome and Firefox) lets you set vim-style keyboard navigation. Keyboard Maestro on Mac and AutoHotkey on Windows are more powerful tools that can create shortcuts across any application, including browsers.

If you want to change a shortcut for a specific website or web application, check whether that site has its own keyboard settings. Gmail, for example, has keyboard shortcuts you can turn on or off in Settings. Some web applications built with frameworks like Electron (Discord, Slack, Visual Studio Code) allow shortcut customization through their preferences, even though they run in a browser-like window.

What to do when a shortcut is already taken

If you try to assign a shortcut that is already in use, the system will usually warn you or prevent you from saving it. You have two options: choose a different key combination, or find and remove the existing shortcut first. In Windows and Mac settings, you can search for the shortcut you want to use and see what action it is currently assigned to, then decide whether to reassign it.

Be cautious about overriding system-level shortcuts. Changing Ctrl+Alt+Delete on Windows or Cmd+Space on Mac might break important functions. If you do override a system shortcut and regret it, you can always reset it back to default — most operating systems have a "Restore Defaults" button in the keyboard settings.

Applications that do not allow shortcut changes

Some programs lock their keyboard shortcuts and do not provide a customization interface. This is common in professional software like certain versions of Adobe Creative Suite, some games, and system utilities. If an application does not have a Preferences section for shortcuts, check the application's documentation or support site to see whether customization is possible through a configuration file.

If you absolutely need to remap shortcuts for a locked application, you can use system-level tools like AutoHotkey on Windows or Karabiner on Mac. These tools intercept keyboard input before it reaches the application, so they can remap keys globally. This approach requires more setup but works around application-level restrictions.

Frequently Asked Questions

Can I use the same shortcut for different actions in different applications?

Yes. A shortcut assigned in one application does not affect others. For example, you can set Ctrl+Shift+K to do one thing in your text editor and something completely different in your email client. The operating system only enforces uniqueness at the system level, not across applications.

What happens if I forget what I changed a shortcut to?

Most operating systems and applications have a "Restore Defaults" or "Reset" button in the keyboard settings. This will revert all shortcuts to their original state. You can also search your keyboard settings by the action name to see what shortcut is currently assigned to it.

Can I export my custom shortcuts to use on another computer?

It depends on the application. Some programs like Visual Studio Code let you export and import keyboard settings. Others store shortcuts in configuration files you can manually copy. System-level shortcuts are usually tied to your user account, so they may not transfer between computers without reconfiguring them.

Why does my new shortcut not work after I set it?

The most common reason is that another application or system process is intercepting the shortcut before it reaches your target application. Try restarting the application or your computer. If it still does not work, check whether the shortcut is already assigned elsewhere by searching your keyboard settings for that key combination.

Can I create a shortcut with more than three keys pressed at once?

Most systems support up to three or four keys in combination — typically Ctrl+Shift+Alt+Key or Cmd+Shift+Option+Key. Some applications allow longer combinations, but they become harder to remember and use. Stick to two or three keys for shortcuts you use regularly.
