How to select multiple text and overlay elements
You can select multiple overlays by clicking and dragging the mouse over the overlays.
This works well if you have to make changes to a group of overlays on your clip - for example, adjusting the overlay duration on a clip or repositioning multiple overlays on your clip.
To make more changes to the selected overlays, click Options from the action bar, and now you can adjust the alignment, color, animation, etc.
