Ranged combat symbols

Those in the lower left, next to your chance to hit - The wall, the eye and the arrow. What do they mean?

 

The wall means that your line of sight is blocked, or that the target has a high enough Magickal Aptitude to affect your chance to hit with your technological weapon (apparently changed to an Arcanum symbol in the unofficial patch). The eye means that your chance to hit is reduced due to long range compared to your Perception, and the bull's eye means that the target is beyond the range of your weapon.

It's all in page 56 of the manual - Examining Creatures in Combat.

 

I somehow overlooked that but im gonna check it out now, thanks
