Oh, sorry, you did say that you can't make any sense of the manual so I wasn't sure what that meant really as going direct to a waypoint is just about the easiest thing you can do with the FMC.  

You are right, if the waypoint isn't in the database then you can't really go to it by name. ;D  If you know what the lat/lon is for it you can add it in this way.  This is what I do if a waypoint on a STAR, for example, is not in the database.  I am not familiar with that "Move" feature.  I always manually enter in all my flight plans so have not imported any in nor run up against this problem really.

I have the not in database problem as I don't update my databases with Navigraph every once in a while but it is not a huge problem as there are a huge number of waypoints in the database. The default database that came with Ver 4.3 seems fairly current to me.  I have to do a lot less of this adding in waypoints by Lat/Lon than I do with other aircraft.

Well...good luck.
