If you're trying to build a layout in GT Title Designer, and you select multiple layers to copy/paste... then you want to move them down or around the previous set, you have to first make sure they are above the order of the layers they were copied from and then click-n-drag to move them resulting to variance from left to right or up/down... The default behavior when selecting layers is that they should be nudge-able with the arrow keys... Currently, I can only get arrows to work if I've already moved the layers via click-n-drag first.
