thumbwheel
Rotating input control
A thumbwheel is a small rotating dial operated by pressing and rolling with the thumb.
Found on electronic devices, mice, and industrial controls, it allows fine adjustments—scrolling, volume control, or setting values: Use the thumbwheel to adjust the brightness.
The design lets users make precise changes with minimal hand movement.
