aaah, good to know :P
Unfortunately, I'm stuck in teh tutorial

I'm on step 4 now, using the chat and such, and I'm suppose to "tune" one of the chats...but I dunno how! >.<
It says: "To tune a radio, click on the radio header you want to tune. Use (left Alt) to bring up the mouse if you are spawned in. A list of available will be shown and you can click the channel you want that radio to be tuned to. Click on the F3 radio header and select the side channel."
I'm guessing that I'm suppose to press left Alt but nothing happens...any ideas?
