A faucet comprising: a spout;a handle;a controller configured to operate the faucet selectively in a first mode of operation and a second mode of operation, the second mode of operation being different than the first mode of operation; anda mode controller configured to change the faucet from the first mode of operation to the second mode of operation in response to substantially simultaneous touching of the spout and the handle when the faucet is in the first mode of operation. 20. The faucet of claim 19, wherein the simultaneous touching of the spout and the handle comprises grasping of the spout and tapping of the handle. 21. The faucet of claim 20, wherein: grasping of the spout comprises a touch of greater than approximately 250 milliseconds; andtapping of the handle comprises at least one touch of less than less than approximately 250 milliseconds. 22. The faucet of claim 20, wherein the tapping of the handle comprises at least two sequential touches. 23. The faucet of claim 19, wherein the mode controller is also configured to change the faucet from the second mode of operation to the first mode of operation in response to substantially simultaneous touching of the spout and the handle when the faucet is in the second mode of operation. 24. A method of operating a faucet including a spout, a handle, a touch control operably coupled to at least one of the spout and the handle, and a proximity sensor having an active state and an inactive state, the method comprising: providing a first mode of operation of the faucet wherein the proximity sensor is inactive;providing a second mode of operation of the faucet wherein the proximity sensor is active;changing to the second mode of operation in response to substantially simultaneous touching of the spout and the handle if the faucet is in the first mode of operation; andchanging to the first mode of operation in response to substantially simultaneous touching of the spout and the handle if the faucet is in the second mode of operation. 25. The method of claim 24, wherein the simultaneous touching of the spout and the handle comprises grasping of the spout and tapping of the handle. 26. The method of claim 25, wherein: grasping of the spout comprises a touch of greater than approximately 250 milliseconds; andtapping of the handle comprises at least one touch of less than less than approximately 250 milliseconds. 27. The method of claim 25, wherein the tapping of the handle comprises at least two sequential touches.
