It would be very helpful if BetterTouchTool’s Application Switcher could support a “gesture mode” when triggered by a mouse button (for example, the middle button on a Logitech MX Master).
The desired behavior is:
- Press and hold a mouse button (e.g. middle button) to open the BTT Application Switcher.
- While holding the button, move the mouse so the cursor hovers over the app icon to select it.
- When the mouse button is released, the switcher should:
• Activate the app currently under the cursor.
• Automatically hide/close, without requiring any additional click.
In other words, the mouse button should behave like a “hold‑to‑switch” gesture: press to show the switcher, hover to choose, release to confirm.
Why this is useful
• This mirrors the behavior many users are used to from Logi Options and similar tools, where the middle mouse button opens the app switcher and releasing the button selects the hovered app.
• It allows fast, one‑handed app switching with minimal clicks and without using the keyboard.
• It makes the App Switcher feel consistent between trackpad/keyboard gestures and mouse gestures, by having a similar “modifier/gesture held → choose → release to select” flow.
Current limitation
• Today, when the Application Switcher is triggered by a mouse button, it stays open after releasing the button and requires an explicit click on the app icon to switch.
• There is no option to “activate hovered app on mouse trigger release,” which prevents fully replicating the Logi Options style workflow for mouse users.
Proposed options / settings
It would be great to have an option like:
• Per‑trigger checkbox:
• “Activate app under mouse when trigger is released (gesture mode)”
or inside the Application Switcher settings:
• “Mouse gesture mode: select hovered app on trigger release”
Enabling this would let users assign a mouse button to the Application Switcher and get the exact behavior described above.
