Glidepad gives touchpad gestures somewhere useful to go

Field notes

Glidepad bases its recognizer on the wheel-event stream that browsers expose instead of a dedicated touchpad API. The page describes separate horizontal and vertical behaviors: double swipes can open assigned destinations, while sharp upward and downward flicks can create or close tabs. Controls include velocity, distance, timing, and velocity-change thresholds, and the live checker reports event count, peak speed, and flicks.
