The Caps Lock key, for many, is a relic of a bygone era. While it once served a vital purpose in the days of typewriters and early computing, its primary function today is often accidental activation, leading to frustrating bursts of uppercase letters in the middle of carefully crafted sentences. If you find yourself constantly battling the Caps Lock key, there’s a solution: repurpose it! This article will guide you through the process of remapping your Caps Lock key to function as an additional Shift key, providing you with greater typing efficiency and reducing those unintentional uppercase outbursts.
Why Remap Caps Lock to Shift?
Think about the ergonomics of your keyboard. The Shift keys are typically located on the far left and right sides, requiring a stretch for your pinky fingers. For extended typing sessions, this can lead to strain and discomfort. The Caps Lock key, however, sits in a more accessible position, directly under your index and middle fingers. By transforming it into a Shift key, you can distribute the workload across more fingers, potentially improving your typing speed and reducing the risk of repetitive strain injuries. Repurposing Caps Lock is about maximizing efficiency and comfort.
Furthermore, for users who frequently utilize the Shift key for shortcuts and commands, having an extra Shift key readily available can significantly speed up their workflow. It’s a small change that can make a big difference in your daily computing experience.
Remapping Caps Lock on Windows
Windows offers several methods for remapping keys, ranging from built-in features to third-party applications. We’ll explore the most popular and effective techniques.
Using the Windows Registry Editor
The Windows Registry is a powerful database that stores low-level settings for the operating system and applications. While directly editing the Registry can be intimidating, it provides a reliable method for remapping keys. Always back up your Registry before making any changes.
Backing Up the Registry
Before diving in, let’s create a safety net. To back up your Registry:
- Press the Windows key + R to open the Run dialog box.
- Type “regedit” and press Enter. This will open the Registry Editor.
- In the Registry Editor, go to File > Export.
- Choose a location to save the backup file, give it a descriptive name (e.g., “RegistryBackup”), and click Save.
If anything goes wrong during the remapping process, you can simply double-click the backup file to restore your Registry to its previous state.
Creating the Scan Code Map
Now, let’s create the necessary entries in the Registry to remap the Caps Lock key:
- In the Registry Editor, navigate to the following key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout - Right-click in the right-hand pane, select New, and then click “Binary Value”.
- Name the new value “ScanCode Map”.
- Double-click the “ScanCode Map” value to open the Edit Binary Value dialog box.
- Enter the following data, being careful to enter each character correctly, including spaces and commas:
00 00 00 00 00 00 00 00 02 00 00 00 2A 00 3A 00 00 00 00 00- The first eight zeros (00 00 00 00 00 00 00 00) represent the header of the ScanCode Map.
- The next four zeros (02 00 00 00) indicate that we’re remapping one key. The “02” signifies that we’re making two mappings (Caps Lock to Left Shift and null mapping).
- “2A 00” is the scan code for the Left Shift key.
- “3A 00” is the scan code for the Caps Lock key. This line tells the system to map the Caps Lock key to function as the Left Shift key.
- The final eight zeros (00 00 00 00) terminate the mapping.
- Click OK to save the changes.
- Close the Registry Editor and restart your computer for the changes to take effect.
After restarting, your Caps Lock key should now function as a Shift key. To revert the changes, simply delete the “ScanCode Map” value from the Registry and restart your computer.
Using Third-Party Key Remapping Software
If you’re uncomfortable editing the Registry directly, several user-friendly key remapping software options are available. These tools provide a graphical interface for assigning new functions to keys, making the process much simpler and less prone to errors.
AutoHotkey
AutoHotkey is a powerful and free scripting language for Windows that allows you to automate tasks and remap keys. While it requires a bit of scripting knowledge, the syntax is relatively straightforward, and numerous online resources are available to help you get started.
To remap Caps Lock to Shift using AutoHotkey:
- Download and install AutoHotkey from the official website (https://www.autohotkey.com/).
- Create a new text file (e.g., “CapslockToShift.ahk”).
- Open the text file in a text editor (like Notepad).
- Add the following lines to the file:
CapsLock::LShift
return - Save the file with the “.ahk” extension.
- Double-click the “.ahk” file to run the script. The AutoHotkey icon will appear in the system tray.
Now, your Caps Lock key should function as a Left Shift key whenever the AutoHotkey script is running. To make the script run automatically at startup, you can create a shortcut to the script and place it in your Startup folder (accessible by pressing Windows key + R, typing “shell:startup”, and pressing Enter).
SharpKeys
SharpKeys is a simple and free utility specifically designed for remapping keys on Windows. It provides a graphical interface for selecting the key you want to remap and the new function you want to assign to it.

- In the right-hand column, select “Left Shift”.
- Click OK.
- Click the “Write to Registry” button.
- Close SharpKeys and restart your computer for the changes to take effect.
SharpKeys modifies the same Registry settings as the manual method described earlier, but it provides a much more user-friendly interface. To revert the changes, simply use SharpKeys to delete the mapping and restart your computer.
Remapping Caps Lock on macOS
macOS provides a built-in mechanism for remapping keys, making the process relatively straightforward.
Using System Preferences
The “Keyboard” pane in System Preferences allows you to modify key mappings without the need for third-party software or complex configurations.
- Click the Apple menu in the top-left corner of your screen and select “System Preferences”.
- Click “Keyboard”.
- Click the “Modifier Keys…” button.
- In the dialog box, select “Caps Lock (⇪) Key” from the dropdown menu.
- Choose “Shift” from the list of options.
- Click OK.
Your Caps Lock key will now function as a Left Shift key. To revert the changes, simply repeat these steps and select “No Action” or “Caps Lock” from the dropdown menu. macOS makes key remapping incredibly simple.
Considerations and Potential Issues
While remapping Caps Lock to Shift can be a beneficial change, there are a few things to consider:
- Muscle Memory: If you’re accustomed to using the Caps Lock key, it may take some time to adjust to its new function as a Shift key. Be patient and persistent, and eventually, the new mapping will become second nature.
- Software Compatibility: In rare cases, certain software applications may not recognize the remapped Caps Lock key correctly. If you encounter such issues, you may need to temporarily disable the remapping for those specific applications. This is rarely an issue these days.
- Shared Computers: If you share your computer with other users, be mindful that the Caps Lock key will function as a Shift key for them as well. Inform them about the change to avoid confusion.
- Accessibility: If you rely on the Caps Lock key for accessibility purposes (e.g., for users with motor impairments), remapping it may not be the best option. Consider alternative accessibility solutions that do not involve remapping keys.
Conclusion
Remapping your Caps Lock key to function as a Shift key is a relatively simple process that can significantly improve your typing efficiency and reduce the frustration of accidental uppercase activations. Whether you choose to edit the Windows Registry directly, use a third-party key remapping tool, or utilize the built-in macOS functionality, the benefits of having an extra Shift key readily available can outweigh the initial adjustment period.

What are the benefits of remapping Caps Lock to Shift?
Remapping Caps Lock to function as an additional Shift key offers several ergonomic advantages. The Caps Lock key is often located in a prime position on the keyboard, easily accessible to the pinky finger. By converting it to Shift, you reduce the strain on your other fingers, especially when typing a lot of capitalized characters or symbols requiring the Shift key.
This can lead to a more comfortable and efficient typing experience. Furthermore, it allows for ambidextrous shifting; you can use the Caps Lock key as Shift while using your other hand for other keyboard functions. This flexibility can be particularly useful for gamers or programmers who frequently use combinations of keys.
Will remapping Caps Lock disable the original Shift keys?
No, remapping the Caps Lock key does not disable your existing Shift keys. It merely adds an additional Shift key to your keyboard layout. The original Shift keys will continue to function normally, providing you with alternative options for activating the Shift functionality.
This means you have the flexibility to use either the traditional Shift keys or the remapped Caps Lock key, depending on your preference and the situation. It is a complementary addition rather than a replacement, offering improved comfort and accessibility without sacrificing existing functionality.
What software or tools are typically used for remapping Caps Lock?
Several software options exist for remapping keys, including the Caps Lock key. On Windows, you can utilize the built-in Registry Editor, although this requires careful attention to detail. Dedicated keyboard remapping software like SharpKeys or AutoHotKey offers a more user-friendly interface.
For macOS, applications such as Karabiner-Elements are popular and provide a wide range of customization options. These tools allow you to easily select the Caps Lock key and assign it to the Shift function without needing to delve into complex system configurations. They also usually provide options to revert the changes easily if needed.
Is remapping Caps Lock to Shift a permanent change?
Whether the remapping is permanent depends on the method you use. If you modify the system registry directly on Windows, or use a system-level remapping utility on macOS, the change is typically persistent and will apply even after restarting your computer.
However, some software offers temporary remapping profiles. These profiles can be enabled or disabled as needed, making the change non-permanent. This is beneficial if you only want to remap the key temporarily or if you share your computer with others who might prefer the original key configuration.
Can I remap Caps Lock to something other than Shift?
Yes, remapping the Caps Lock key is not limited to just assigning it to the Shift function. You can remap it to virtually any other key or keyboard function according to your personal preferences and needs. Many users find it useful to remap it to frequently used keys, such as Ctrl, Alt, or Esc.
The flexibility of remapping software allows you to tailor your keyboard layout to your specific workflow. You can even assign it to a combination of keys or a macro, further enhancing its utility and streamlining your tasks. Experimenting with different remappings can significantly improve your typing efficiency and comfort.
Are there any potential drawbacks to remapping Caps Lock?
One potential drawback is the initial adjustment period. Muscle memory can be strong, and it may take time to get used to using the Caps Lock key as Shift, especially if you frequently use it for its original purpose. Accidental activations of the Caps Lock function during this transition are common.
Another minor issue is that you effectively lose the original Caps Lock functionality. If you occasionally need to type in ALL CAPS, you’ll need to find an alternative method, such as using the Shift key combined with individual capital letters. However, for most users, the benefits of having an additional Shift key outweigh these minor drawbacks.
Will remapping Caps Lock affect different user accounts on the same computer?
The impact on different user accounts depends on the method used for remapping. If you modify the system registry on Windows, the change typically applies to all user accounts on that computer. Similarly, some system-level remapping utilities on macOS will affect all users.
However, certain software offers the option to configure remapping on a per-user basis. This is useful if different users have different keyboard preferences. Check the settings of your remapping software to determine whether the changes are applied globally or locally to the current user account.
