# Objective The goal of this PR is to receive touchpad magnification and rotation events. ## Solution Implement pendants for winit's `TouchpadMagnify` and `TouchpadRotate` events. Adjust the `mouse_input_events.rs` example to debug magnify and rotate events. Since winit only reports these events on macOS, the Bevy events for touchpad magnification and rotation are currently only fired on macOS.
