Hello everyone! 🌟

What is ThumbSense?

With ThumbSense, you can use your laptop's touchpad as an additional modifier key.
Assign specific keys as mouse buttons and toggle their functionality based on whether your thumb is touching the touchpad. This feature allows you to keep your hands on the home position of the keyboard.
By turning off the often troublesome "tap to click" feature, you can achieve a more comfortable touchpad experience.

Repository

Thumbsense is implemented as a plugin of fusuma.
