Go Around mode
On my type (DH8D), the procedure is:
Pilot (either one as necessity dictates) calls "go around"
Pilot flying pushes the TOGA button to automatically change the flight director to HEADING and PITCH mode, disconnects the autopilot if it was engaged, advances the power levers, pitches the nose smoothly up to an appropriate attitude, calls for flaps and gear to be set as appropriate by the assisting pilot.
The height you climb to and route flown depend on the airport and runway, but at the end of the sequence you would most likely be clean or first stage of flaps, at a set altitude, autopilot re-engaged, and planning on another approach shortly, a hold, or a diversion, depending on why you went around in the first place.
Much abridged and simplified, but I do wonder what you have heard and from whom.
