Using Acrobat Action Wizard to auto-tab to next field

I’m trying to speed up the process of creating an interactive pdf form in Adobe Acrobat through Action Wizard using Javascript, as I use and change the forms many times a day. I’m struggling to make the auto tab work through Action Wizard – I have some fields that require only one number and I like it to automatically go to the next field once that number is entered. Example of some of the code I currently use in Action Wizard:

for (var i = 0; i < numFields; i++) {
  var fName = getNthFieldName(i);
  var f = getField(fName);
  var fTool = getNthFieldName(i).userName;

  if (fName == "C1”) {
  f.charLimit = 1;
  f.alignment = "center";
    f.setAction("Keystroke", "AFNumber_Keystroke\(0, 0, 0, 0, \"\", false\);");
  }
  if (fName =="C2”) {
  f.charLimit = 1;
  f.alignment = "center";
    f.setAction("Keystroke", "AFNumber_Keystroke\(0, 0, 0, 0, \"\", false\);");
  }

}

So I would like C1 to have some code that automatically goes to C2. Is there any way this is possible with just Action Wizard? Currently I’ve been doing it manual using:

function tab_next(next_field_name) {
    if (event.willCommit || AFMergeChange(event).length === event.target.charLimit) {
        getField(next_field_name).setFocus();
    }
}

And the Keystroke script:

tab_next(“C2”);

If anyone knows a way to do this, that would be much appreciated. Thanks!
