that worked borke thanks. i put /bind mouse2 +button5

the servers names are usually things like 'hook and rail' or 'rail and rocket and hook' where you can use only the rail gun and grappling hook, but i dont know how to use the hook. it says bind mouse2 and button 5. what does that mean.. and what is button 5

i am kinda new 2 quake iii arena at least to playing online. the only thing i cant figure out how to do is use the hook in rail'n'hook type of games online. its not like regular, where it is a weapon you switch to, and i tried pressing about every key..
