A technique for implementing a center key in a capacitive sense radial slider interface without use of center mechanical button. A user interaction with an array of capacitive sensors within the radial slider interface is sensed. It is determined whether at least a threshold number greater than one of the capacitive sensors within the array are concurrently actuated by the user interaction. A center key actuation is registered if at least the threshold number of the capacitive sensors are concurrently actuated.
