Lock onto an object.
This will lock your ship onto the object nearest the mouse cursor. If the object
is a planet, your course will change and you will be placed into orbit around
the planet when you arrive. If the object is a ship, you will start receiving
the ships 'vital statistics' as detailed in the Screen Layout section.
This lock will also roughly double you phase's hit angle, and again roughly
double your chance of getting a sensor penetration of their cloaking device
if they activate it while you have the lock.
To break the lock, just set course normally. You cannot lock
onto cloaked ships.
