Change Cursor Key Increments from script

Hey!

I wanna share script for changeing cursor key increment.

/*1*/ // Save to preferences

//tomaxxiINCR.jsx
//An InDesign CS3/CS4/CS5 JavaScript

if (app.dialogs.length > 0) app.dialogs.everyItem().destroy();

if (Number(app.version.split(".")[0]) < 5){
     alert("Script is not compattible");
}else{
    if (app.documents.length != 0){
        ChangeIncrement();
    }else{
        exit();
    }
}
