In particular, a remote control comprises a set of hard keys comprising channel group keys and volume group keys and a set of soft keys activated via a touch screen display. The display identifies the device the volume group keys are set to control and the device the channel group keys are set to control. Selecting the device currently controlled by the channel group keys by, for example, depressing the device indicator on the display screen, initiates a set up mode that displays numerous devices that may be controlled by the channel group keys. Selecting one of the numerous devices assigns the channel group keys to that device. ## Claims ### Claim 1 A controlling device comprising: a plurality of keys comprising a first control group of keys and a second control group of keys; a first device type indicator of a first plurality of device type indicators, wherein the first plurality of device type indicators correspond to devices the first control group of keys may be set to control and the first device type indicator is visually associated with the first control group of keys, whereby a user may readily discern which device the first control group of keys is set to control based on the first device type indicator visually associated with the first control group of keys; a second device type indicator of a second plurality of device type indicators, wherein the second plurality of device type indicators correspond to devices the second control group of keys may be set to control and the second device type indicator is visually associated with the second control group of keys, and a user may readily discern which device the second control group of keys is set to control based on the second device type indicator visually associated with the first control group of keys; a first plurality of device type keys corresponding to devices the first control group of keys may be set to control upon selection of one of the first plurality of device type keys; a second plurality of device type keys corresponding to devices the second control group of keys may be set to control upon election of one of the second plurality of device type keys; and wherein the first plurality and the second plurality of device type keys are soft keys and wherein the first device type indicator is different from the second device type indicator. ### Claim 2 (depends on 1) The controlling device as recited in claim 1, wherein the first plurality of device type keys is the same as the second plurality of device type keys. ### Claim 3 (depends on 1) The controlling device as recited in claim 1, comprising a touch screen, wherein the soft keys, the first device type indicator, and the second device type indicator are displayed on the touch screen. ### Claim 4 (depends on 3) The controlling device as recited in claim 3, wherein the first plurality of device type keys are displayed in response to a user selecting the first device type indicator. ### Claim 5 A remote control comprising: a first control group of keys set to control one of a plurality of devices; means for indicating to a user which of the plurality of devices the first control group of keys is set to control; a second control group of keys set to control one of a plurality of devices; means for indicating to a user which of the plurality of devices the second control group of keys is set to control; means for setting the first control group of keys to a different one of the plurality of devices; means for indicating to a user a selection comprising the plurality of devices from which the user may select the different one device; and means for indicating to a user in which master mode the remote control is set; wherein the means for indicating which device is controlled by the first control group of keys, the means for indicating which device is controlled by the second control group of keys, and the means for indicating the master mode are adapted to operate simultaneously. ### Claim 6 A controlling device, comprising: a plurality of function keys including a first group of function keys actuatable to command volume functions of a plurality of different appliances and a second group of function keys actuatable to command tuning functions of a plurality of different appliances; a plurality of device keys actuatable to select one of the plurality of different appliances as an appliance to be commanded upon actuation of the first group of function keys and actuatable to select one of the plurality of different appliances as an appliance to be commanded upon actuation of the second group of function keys; a first device type indicator visually associated with the first group of function keys to indicate to a user to which one of the plurality of different appliances was selected to be commanded upon actuation of a function key selected from the first group of function keys; a second device type indicator visually associated with the second group of function keys for indicating to a user which one of the plurality of different appliances was selected to be commanded upon actuation of a function key selected from the second group of function keys; and a third device type indicator for indicating to a user which one of the plurality of different appliances will be commanded upon actuation of a function key other than a function key selected from the first group of functions keys and the second group of function keys. ### Claim 7 (depends on 6) The controlling device as recited in claim 6, wherein the function keys comprise hard keys. ### Claim 8 (depends on 7) The controlling device as recited in claim 7, wherein the plurality of device keys comprise soft keys displayed using a touch screen. ### Claim 9 (depends on 8) The controlling device as recited in claim 8, wherein the first device type indicator is displayed in the touch screen in a location visually linked to the first group of function keys and the second device type indicator is displayed in the touch screen in a location visually linked to the second group of function keys. ### Claim 10 (depends on 6) The controlling device as recited in claim 6, wherein each of the function keys includes indicia representative of one or more functions to be commanded upon actuation of the function key. ### Claim 11 (depends on 6) The controlling device as recited in claim 6, wherein the first device type indicator and the second device type indicator each comprises alphanumeric symbols. ### Claim 12 (depends on 6) The controlling device as recited in claim 6, wherein the plurality of device keys are made available for actuation upon a user placing the controlling device into a setup mode. ### Claim 13 A controlling device, comprising: a plurality of function keys including a first group of function keys actuatable to command volume functions of a plurality of different appliances and a second group of function keys actuatable to command tuning functions of a plurality of different appliances; a plurality of device keys actuatable to select one of the plurality of different appliances as an appliance to be commanded upon actuation of the first group of function keys and actuatable to select one of the plurality of different appliances as an appliance to be commanded upon actuation of the second group of function keys; a first device type indicator visually associated with the first group of function keys to indicate to a user to which one of the plurality of different appliances was selected to be commanded upon actuation of a function key selected from the first group of function keys; and a second device type indicator visually associated with the second group of function keys for indicating to a user which one of the plurality of different appliances was selected to be commanded upon actuation of a function key selected from the second group of function keys; wherein the first device type indicator is displayed in a touch screen in a location visually linked to the first group of function keys and the second device type indicator is displayed in the touch screen in a location visually linked to the second group of function keys and wherein the first group of function keys and the second group of function keys are contemporaneously available for actuation by a user and the first device type indicator and the second device type indicator are contemporaneously displayed. ### Claim 14 (depends on 13) The controlling device as recited in claim 13, wherein the function keys comprise hard keys. ### Claim 15 (depends on 13) The controlling device as recited in claim 13, wherein the first device type indicator and the second device type indicator each comprises alphanumeric symbols.
