in a similar way you can write scripts that chance your force setup to a few presets you use a lot, so you don't have to go to the menu when you want to switch.
Like said before, a script is only a set of chained commands, nothing you can't do through normal key pressing. Furthermore, a script has a huge disadvantage, once you start it, you can't stop it..
I was dueling a person once that used the helicopter move, but had the spin last a little to long, result, he was stuck in the spin long enough to get his ass killed when he used it. The same goes for every scripted combo, if it goes wrong, you can't abbort the move, something a player who doesn't script can.
