// this snippet will set a defined value on the selected properties at the current time of the comp

// add this code to a JAVASCRIPT button in ft-toolbar
// SET myValue like you wish



// myValue is the value which will be applied to the selected properties
// the value could be one of the following (just un-comment one of them) : 
var myValue = 1.0; // a float number
// var myValue = 100; // a integer number
//var myValue = [0.5 ,10.0]; // an array of 2 elements - for instance X & Y axis
// var myValue = [0.5 , 4.0 , 7.0]; // an array of 3 elements - for instance X, Y & Z axis
// var myValue = [1.0 , 1.0 , 1.0,1.0]; // an array of 4 elements - for instance a color as RGBA
