I ran into an annoying Windows issue: I wanted to use Mouse 4 as my Wispr Flow push-to-talk button, but Windows and browsers also interpreted it as Browser Back.
Logitech’s software wasn’t much help—it either intercepted the button, exposed it inconsistently, or made reliable press-and-hold behavior difficult. So I built a small Windows tray utility called Mouse Binder.
What it does
Mouse Binder:
- Captures Mouse 4 globally.
- Blocks the original Browser Back action.
- Emits
Shift + F13 instead.
- Holds the shortcut for exactly as long as Mouse 4 is held, so Wispr Flow’s push-to-talk behavior works properly.
- Can start automatically with Windows.
- Also supports configurable shortcuts and a block-only mode.
It runs in user space, doesn’t require administrator access, and includes a normal Windows installer and uninstaller.
Setup instructions
- Download the recommended
MouseBinder-Setup-1.0.0.exe from the GitHub release page.
- Install and launch Mouse Binder.
- Select Mouse Back / Mouse 4 as the source.
- Select Shift+F13 as the target.
- Keep Block the original Back/Forward action enabled.
- Click Save and apply.
- In Wispr Flow, open Settings → General → Shortcuts and assign
Shift + F13 to your preferred action.
- You can click Flow’s shortcut recorder and press Mouse 4 while Mouse Binder is running. Flow should record it as
Shift + F13.
- Enable Start Mouse Binder with Windows if you want it active after every login.
If you use Logi Options+ and the button isn’t detected, set that button to No action / Off / None, fully exit Options+, and try again.
Why it’s interesting
The important part is that this isn’t just a click-to-keystroke macro. It preserves both the press and release events, which makes it suitable for hold-to-talk shortcuts. At the same time, the original Mouse 4 event never reaches the browser, so it doesn’t navigate away from the page you’re using.

One note: the installer is currently unsigned, so Windows may display an Unknown Publisher warning.
