For the record I like to heal out in the open waiting to get pounced, sadly hunters don't go for me unless i'm smoked or charged or boomed and horde on me and carlos is probably chasing a smoker and not helping me(btw that has happened).
!points - !buy - !sp - !ammo - !heal and !laser are the basic when it comes to binds, i for one use close to 20 binds cause well why not.
bind "2" "sm_buy" replace buy with any of the basic along with the number or letter if you'd like and type it in console.
