for Zero

If one needs to connect different devices to a Raspberry Pi Zero but want's to use just one USB port one would use an USB On-The-Go (OTG) cable.

An other possibility would be this small hack: one can solder a wire between the USB sense pin PP40 (of USB J10) and the ground pin PP6 on the Raspberry Pi. That way every USB cable on the USB socket J10 (not “Power In”) act like an OTG cable.
