I like the ezQuake default /builtin script:

alias +axe "weapon 1;+attack"
alias -axe "-attack"
alias +gl "weapon 6 5 3 2 4 1;+attack"
alias -gl "-attack"
alias +lg "weapon 8 5 3 2 4 1;+attack"
alias -lg "-attack"
alias +ng "weapon 4 5 3 2 1;+attack"
alias -ng "-attack"
alias +rjump "weapon 7;+attack;+jump"
alias -rjump "-attack;-jump"
alias +rl "weapon 7 6 5 3 2 4 1;+attack"
alias -rl "-attack"
alias +sg "weapon 2 3 5 4 1;+attack"
alias -sg "-attack"
alias +sng "weapon 5 3 2 4 1;+attack"
alias -sng "-attack"
alias +ssg "weapon 3 2 5 4 1;+attack"
alias -ssg "-attack"
alias +zoom "set oldfov $fov;lowsenscalc;fov 80;wait;fov 70"
alias -zoom "normalsenscalc;fov 95;wait;fov $oldfov"

What would be the equivalent in Q3A? or CPMA/OSP?
