InputActions

Linux utility for binding keyboard shortcuts, mouse gestures, touchpad gestures and touchscreen gestures to system actions, created with flexibility in mind.

Supported environments: Plasma 6, Hyprland, GNOME, other Wayland compositors (availability of extra features depends on implemented protocols), X11 (base features only)

Features

• Supported device types: keyboard, mouse, touchpad, touchscreen
• Input event filtering
• Uses libinput, which handles device quirks
• Complementary evdev input backend for better touchpad support (may be disabled in case of issues)
• Conditional triggers
• Built-in action for simulating keyboard and mouse input
