The same LCD menu structure applies to all the (RAMPS, RAMBO, RUMBA) electronics boards. Manually extruding via the LCD is on the same move axis menu - just scroll down to see the Extruder option. Like the Z axis, extruder moves are only allowed for the 0.1mm and 1mm step size menu options. Also note that firmware will prevent you from moving the extruder motor unless the hot end is above a minimum temperature.
