What does the Yellow gun do?

[Varzin]

*SPOILERS* If you don't have the yellow gun don't read this.

I just got the yellow gun and was confronted with the first yellow wall just after recieving the gun, the one that has the little mouse on the wall intended to tell me how to use the new gun. The mouse graphic has the scrollwheel highlighted and the text "Middle Mouse." However, whether I click, roll, or hold click and roll, it doesn't appear to do anything.

Do I need to change some setting to allow use of this button in game or somthing? I'm not even sure what it's supposed to do so any information would be helpful, thank you.

You just hold middle click on top of a cube, then, while holding middle mouse, move to an area that doesn't have any cubes in it. (You can also use CTRL if you don't like middle mouse)

Ah I got it now, using CTRL worked, thank you. For some reason the game isn't recognizing my scroll wheel because that doesn't do anything at all. Thanks again for the help. (^_^)

Likely Microsoft Intellipoint or whatever mouse softare you use is defaulting the Middle Button to behaving like something other then the middle button.

It may be that your middle button is broken. My middle button broke even though I could still scroll. Consider getting a new mouse if this a reccurring problem.
