How to Bind Mouse Buttons to Hotkeys in OBS Studio

This guide provides a straightforward walkthrough on how to map your mouse buttons to hotkeys in OBS Studio. You will learn the standard process for assigning mouse clicks to actions like starting a stream, muting your microphone, or switching scenes, as well as how to resolve issues if OBS does not natively recognize your specific mouse buttons.

Step-by-Step Guide to Binding Mouse Buttons in OBS

OBS Studio natively supports standard mouse clicks (like Left Click, Right Click, Middle Click, Mouse 4, and Mouse 5) for hotkey assignments. Follow these steps to bind them:

  1. Open OBS Studio and click on Settings in the bottom-right Controls dock (or go to File > Settings in the top menu).
  2. In the Settings window, select the Hotkeys tab from the left sidebar.
  3. Scroll through the list to find the specific action you want to bind (for example, “Mute” under your Microphone source, or “Switch to Scene”).
  4. Click inside the input field next to the desired action.
  5. Press the mouse button you want to assign to that action. The field should display the name of the button (e.g., Mouse 4 or MB4).
  6. Click Apply and then OK to save your changes.

Troubleshooting Unrecognized Mouse Buttons

If you have a gaming mouse with many side buttons, OBS Studio might not register inputs beyond the standard Mouse 4 and Mouse 5. If clicking your mouse button in the hotkey field does nothing, you can bypass this limitation using your mouse’s configuration software:

  1. Open your mouse software (such as Logitech G HUB, Razer Synapse, Corsair iCUE, or SteelSeries GG).
  2. Select your mouse and locate the profile or button assignment settings.
  3. Select the specific mouse button that OBS failed to recognize.
  4. Rebind that mouse button to a keyboard key or key combination that you rarely use (such as F13 through F24, or a combination like Ctrl + Shift + Alt + O).
  5. Return to OBS Studio > Settings > Hotkeys.
  6. Click the input field for your desired action, then press the mapped mouse button. OBS will register the keyboard shortcut you assigned to it, allowing you to use your mouse button seamlessly.
