This can be used to choose the weapon the CPU or human opponent uses, if he or she is unaware. You can also use the same weapon repeatedly. First, click the weapon box to bring up the list, then move to a weapon that you want to fire so that it is blinking yellow. Then press [Space] to fire. It will keep the menu up, but launch the weapon you highlighted. Next, move to a different weapon. It will take that weapon instead of the fired one. If you keep the list up, it will stay up while the computer is taking his turn. You can move the list to a weapon you want him to fire. Note: The weapon in the CPU's list that is solid yellow is the one it will fire if you take too long.
