//Indifferences
We found sometimes we had controls left over such as his mouse3 being bound to +jump but i did not wish to have mouse3 bound at all.

I set up an indifferences section for the script to make sure these extra settings were fixed when we changed control set.

alias Set1Indifferences "unbind mouse3; unbind capslock;"
alias Set2Indifferences "bind mwheelup invprev; bind mwheeldown invnext;"

//Combine controls into player names for toggling
alias Player1Name "Set1Jumps; Set1Crouch; Set1Use; Set1QuickChange; Set1Scores; Set1BuyMenu; Set1Sensitivity; Set1Indifferences;"
alias Player2Name "Set2Jumps; Set2Crouch; Set2Use; Set2QuickChange; Set2Scores; Set2BuyMenu; Set2Sensitivity; Set2Indifferences;"

//The toggler
alias controlset Player1Controls
alias Player1Controls "Player1Name; alias controlset Player2Controls;"
alias Player2Controls "Player2Name; alias controlset Player1Controls;"

//The bind
bind * controlset

Now you can instantly switch between control sets by hitting the * key on the numpad!

Hope this helps (:
