Narrative:

On takeoff roll at transition speed; we experienced a wind shear alert from the on-board detection system. We both looked down and saw normal acceleration on our airspeeds and I decided to continue the takeoff; first officer (first officer) agreed out loud. Rotation was normal; and the initial climb through gear retraction was normal.at 400 feet first officer called navigation; but I mistakenly put the aircraft in heading mode. We were both placing heavy emphasis on our airspeed; vertical climb and pitch in case we had another shear.I had to clear the wind shear effects; reset the art system; go around power and 'wings level' mode. And I was busy thinking about how to reset everything as we climb through efca.at 1000 feet; first officer called for vertical speed one half; climb power; and VNAV.I set all of these modes and just a moment later; I noticed that the aircraft hadn't turned right at leeln intersection and was continuing straight out on runway heading.I reached up and began to turn the aircraft in heading mode to the right to catch the STAAV6 course.as I did; ATC gave a terrain alert and had us continue our turn to 050 degree heading.ATC asked me to call them when we landed and I had a discussion with him about wind shear mode; and how it discards your power; pitch; and navigation modes and that you must manually place the aircraft back into the proper modes after the event at that the distraction took us a bit through course. I assured him that we were in the process of a course correction when he called and he advised that we 'keep ATC informed' when you have a distraction; even if it wasn't a significant wind shear. I agreed and informed him I would submit this report. In training; we all have experienced wind shear and the recovery technique; usually though 'positive rate; gear up'.during these exercises; usually; 'the sky is yours' because you are experiencing an emergency.there may be several more steps following a wind shear event if you are in the vicinity of terrain; or on an arrival or departure procedure that you must quickly follow up with; ....resetting pitch power; navigation; and configuration.looking back; I would have informed ATC that we had a wind shear event on takeoff. Although I discounted it as 'insignificant'; that may have given us some more lee-way in handling the recovery.

Title: MD80 Captain experienced a windshear alert during takeoff and elected to continue; due to the lack of any airspeed fluctuations in the cockpit and no visible weather ahead. Resetting the automation after the event took some time and resulted in a deviation from the intended flight path. ATC issued a terrain alert as a turn was initiated.
