Movement
From Guild Wars Wiki
Movement of characters is controlled by means of the movement keys, or by using the mouse. Mouse movement uses path planning to move the character to the clicked destination in the most efficient path.
You can also press the "R" key, which will enable your character to run automatically. This is useful while trying to communicate with other players.
Heroes and henchmen who by default always follow their human counterpart, can only be moved seperately by means of waypoints set with the mouse.
