Example of classes.cfg

echo SNIPER CFG LOADED

alias sniperg "slot2; bind MOUSE4 ar"
alias ar "slot3; bind MOUSE4 sniperg"
bind "MOUSE4" "sniperg"
bind "MOUSE5" "slot4"

echo ENGINEER CFG LOADED

alias gpipe "slot3; bind MOUSE4 bpipe"
alias bpipe "slot1; bind MOUSE4 gpipe"
bind MOUSE4 gpipe
bind "MOUSE5" "slot2"

and in CFG i use bind "MOUSE4" "rpg"

not sure if its right :P

i use mouse 4 to change between my prefered 2 weapons of each class and mouse 5 to use the less powerfull weapon, for when i run out of reload.
