A:Answer Hey there! You can manually power off the devices or customize the inactivity timing through the Logi Options+ software so that the devices goes inactive when ever you want it to. About the Copy/Paste, if the keyboard fails to correctly detect the operating system of a device, you can manually select the operating system by performing a long press (3 seconds) of a function key combination. For Windows/Android, the combination keys are fn+P and for MacOSX/iOS, it is fn+I.
