LinguaX is a macOS menu bar app that enhances third-party mice with smooth scrolling, button mapping, push-to-talk voice input, and automatic input source switching.
Mouse+ Enhancement
- Smooth Scrolling: Tunable scroll curve for any USB or Bluetooth mouse, with controls for step size, speed gain, and inertia duration. Per-app overrides available.
- Gesture & Button Mapping: Map clicks, long-press, and directional drags to actions like app launch, system controls, media, or custom scripts.
- App-Scoped Overrides: Override any button or scroll behavior for a specific app without changing global config.
Push-to-Talk Voice Typing Hold a mouse side button to start macOS dictation instantly. Release to stop. Works with macOS Dictation, Wispr Flow, superwhisper, and any push-to-talk app.
Automatic Input Source Switching Set rules per app and per website domain. LinguaX switches input source automatically whenever context changes, falling back to your default when no rule matches.
