Turn the edges of your MacBook trackpad into controls
Grounded in available product and source data
Padrail gives the rim of your MacBook trackpad a purpose. The sides handle the sound level and the screen brightness, the lower rim adjusts the backlight under the keys, and the upper rim adapts to whichever app you have open.
A single finger on the rim is enough to make the change, with a haptic tick at each step and no drift of the pointer. Scrolling, clicking and other gestures keep working, and you can narrow the rims, change what each one does, or turn it off.
