How do I customize buttons on the Corsair Harpoon?

Last updated: September 2025
Problem
The Corsair Harpoon Wireless Mouse includes multiple programmable buttons. By default, these control standard functions (click, scroll, DPI switch, side buttons). Without customization, you may not be getting the most out of the mouse for gaming or productivity.
Solution
You can customize button functions on the Corsair Harpoon using Corsair iCUE software, which allows remapping to keystrokes, macros, or system functions.
Step-by-step instructions
Accessing iCUE
- Connect the Harpoon Wireless Mouse to your PC (via USB, dongle, or Bluetooth).
- Open the Corsair iCUE software.
- Select the Harpoon Wireless Mouse from the device list.
Remapping buttons
4. Navigate to the Key Assignments section.
5. Select the button you want to customize (e.g., side buttons, DPI switch).
6. Choose a new function from the list:
- Keyboard input (e.g., assign a key press)
- Mouse function (e.g., double-click, middle-click)
- Macro (recorded sequence of actions)
- Media control (e.g., volume, play/pause)
- Application launch (open a specific program)
- Save your changes.
Creating profiles
8. Set up multiple profiles for different games or tasks.
9. Save them either in iCUE software or to the mouse’s onboard memory.
10. Switch profiles manually in iCUE, or allow iCUE to switch automatically when launching certain applications.
Optional methods or tools
- Onboard memory profiles: Store custom button setups directly on the mouse for use on PCs without iCUE installed.
- Game-specific profiles: FPS games (quick actions on side buttons) vs. productivity apps (shortcuts for copy/paste).
Best practices or tips
- Keep at least one button as DPI shift or profile switch for quick sensitivity changes.
- Avoid overwriting the left and right click unless you have a specific use case.
- Test new mappings in a simple program before relying on them in competitive games.
- Use macros responsibly — some online games restrict them.
