WEAPON SELECTION PRECEDENCE MENU
This menu lets you configure how your ship switches between weapons when
(a) you hit the "Cycle Primary" or "Cycle Secondary" keys to cycle through
your weapons; (b) when you run out of ammo with one weapon and the ship
switches to another; and (c) when you pick up a new weapon.
To configure the weapons' priorities, click on one weapon and a window will
appear to allow you to select another weapon to have them switch places.
Items at the top of the column have the lowest priority.
For instance, if you want Homing Missiles to have priority over Frag Missiles,
click "Homing" and then click "Frag", so that "Frag" is listed higher in the
column than "Homing". This sets Frag to have lower priority. Now, if you
have Frag Missiles armed and you run across your first Homing Missile, you
will auto-switch to the Homing Missile. If you had set Homing Missiles to be
lower priority, then running across your first Homing Missile would not trigger
an auto-switch. To disable a weapon entirely from your weapon selection
press the TAB corresponding to the weapons name.
