Can you INTERACT with script without mouse on click?

Question

Hi everyone,
I got this script
has a dropdown list inside
I can run it in win 7 and interact with by keyboard without mouse
but why I can't do same thing in the MAC?
var
  mySelected = Number( app.extractLabel("mDialog") ),
  myDialog = app.dialogs.add({name:"Indesign Close and Save File Machine",canCancel:true});
  with(myDialog){
       with(dialogColumns.add()){
            with(dialogRows.add()){
                 var
                 mySelection = dropdowns.add({stringList:["01   Close and SAVED", "02   Close WITHOUT save", "03   Save all files", "04   Reverse", "05   Remove unused color"], selectedIndex: 0});
if (myDialog.show() == true) {  
    var docs = app.documents;  
    main();  
    myDialog.destroy();  
function main(){
      colse_file();
function colse_file(){
    if (mySelection.selectedIndex == 0){
        var docs = app.documents;
             for (var i = docs.length-1; i >= 0; i--) {
                     docs[i].close(SaveOptions.YES);
      alert("Files are saved.") 
      return;
    if (mySelection.selectedIndex == 1){
        var docs = app.documents;
        for (var i = docs.length-1; i >= 0; i--) {
              docs[i].close(SaveOptions.NO);
      alert("Files are closed without save.") 
      return;
   if (mySelection.selectedIndex == 2){
        var docs = app.documents;
             for (var i = docs.length-1; i >= 0; i--) {
                     docs[i].save();
      alert("Files are saved.") 
      return;
   if (mySelection.selectedIndex == 3){
      var docs = app.documents;
             app.scriptPreferences.userInteractionLevel = UserInteractionLevels.neverInteract;
             app.documents.everyItem().revert();
             app.scriptPreferences.userInteractionLevel = UserInteractionLevels.interactWithAll;
      alert("All files are reversed.") 
      return;
   if (mySelection.selectedIndex == 4){
      var doc = app.documents, i, j; 
           for(i =0;i<doc.length;i++) 
                  unused = doc[i].unusedSwatches; 
                     for(j=0;j<unused.length;j++) 
                      unused[j].remove(); 
        alert("All the unused swatches in your opening files are removed.") 
      return;
thanks

The only way to purchase from the iTunes Store is via iTunes, on a computer or iOS device, and it will automatically download your purchase immediately. You have a couple of options: you can go ahead and purchase on another computer that has iTunes and then just copy the purchases to your Vista system (via any normal means of file transfer), or if you're in the US, the new iTunes in the Cloud feature, currently in beta and so not completely reliable, would allow you to download the purchases again at some future time when you get your iTunes problems sorted out. I'd recommend the first option as the best solution for now (and the only solution if you're not in the US).
