Script to enable/disable audio/videotracks

Question

Hi,
Trying this:
function SwitchOffVideoOutput (vtracks,activeSeq)
       var active_seq = activeSeq;
       var videotracks = active_seq.videoTracks;
       alert("numTracks: "+ videotracks.numTracks);
       track = vtracks.split("|");
       for (i=0; i <= track.length; i++) {
      alert("Switching off: "+ track[i]);
      // Would like to do something like this:
      // videotracks[track].enabled=false;
      // videotracks[track].output=false;
      // Renaming sequence from A to B
      tmp = active_seq.name;
      tmp = tmp.replace("_A","_B");
      alert(tmp);
      //active_seq.name = tmp;
SwitchOffVideoOutput ("2|3|4",app.project.activeSequence);
// But also would like to do this:
var myColl = app.project.selection;
for (i=0; i <= myColl.length; i++) {//loop through the project
     alert(myColl.name)
     SwitchOffVideoOutput ("2|3|4",myColl.name);
// SwitchOffVideoOutput and rename selection in Premiere Pro

Although you can set or remove the Dark interface style with defaults write syntax, the reset back to default (non-dark) interface will require a log-out/log-in cycle to entirely remove the Dark style. Toggling this style on and off in the System Preferences > General panel does not require the preceding log-out disruption. Unfortunately, other than possible GUI scripting, the Apple Script dictionary in Yosemite is very limited with respect to System Preferences access, and enabling/disabling the dark interface style.
