Translating a selection

[cwodwrth]

I'm trying to translate a selection (which is NOT a quadrangle, rather the outline of some text) and I'm getting the following error....

Error 8800: General Photoshop error occurred. This functionality may not be available in this version of Photoshop.
- The command "Transform" is not currently available:
Line: 574
-> selRef.translate(1,0);

(It should also be noted that the error message is referring to the "Transform" command rather than "Translate", but I imagine this is because translation is a transformation function.)

Is this actually true that we can't translate selections? Or is my syntax wrong? Is there an alternative way to translate? I've tried changing the bounds, but:

a) It doesn't see to actually move the selection

b) I'm not sure how moving the bounds would effect the selection anyway since it is not a quadrangle, but the outline of the text.

If translate doesn't work, maybe there is a way to nudge it? Although I imagine behind the scenes that is the same operation.

Any wisdom out there?

moveSelection(100, -20);

function moveSelection(_x, _y) {
    var desc1 = new ActionDescriptor();
    var ref1 = new ActionReference();
    ref1.putProperty(charIDToTypeID('Chnl'), stringIDToTypeID("selection"));
    desc1.putReference(charIDToTypeID('null'), ref1);
    var desc2 = new ActionDescriptor();
    desc2.putUnitDouble(charIDToTypeID('Hrzn'), charIDToTypeID('#Pxl'), _x);
    desc2.putUnitDouble(charIDToTypeID('Vrtc'), charIDToTypeID('#Pxl'), _y);
    desc1.putObject(charIDToTypeID('T   '), charIDToTypeID('Ofst'), desc2);
    executeAction(charIDToTypeID('move'), desc1, DialogModes.NO);
}

This works, but is there not a native call? I was really hoping for something that didn't update the history state such as when simply move a selection around using the arrow keys, you get one "Nudge Outline" entry and that's it, rather than a ton of "Move Selection" entries.

You can suspend history before using Photoshop features that create history states. Even a native DOM method like Resize would create a history state. Also nudge does create history states. You can easily see  how susspend history  work in this script.
