Thanks, I will try this exactly as you mentioned. BTW, I have tried this before but not exactly the way you described. Used VNAV LNAV with left autopilot button but the plane kept going straight and up. Turns out that the first waypoint was exactly on the south side while I was flying north because of the allocated runway. As soon as I followed ATC advice to take southern heading, I was able to capture it.

Also, besides helping me tide over, if you can add this little piece in your tutorial, perhaps, this will not get asked over and over again in the forums.
