An example electronic device may include a display module, a communication module, a physical input device, and a processor. The processor may detect a trigger related to external device control from the electronic device and identify a capability to be controlled by the external device, based on the detection of the trigger. The processor may change a first function configured to cause a designated physical input device of the electronic device to operate, to a second function related to control of the identified capability of the external device and control the capability of the external device on the basis of detection of a user input through the physical input device.
