Need technical support – Tanach Bible - the Hebrew/English Bible Review

I recently purchased this app, and I cannot seem to find a way to highlight selected passages. I like the side by side English and Hebrew reading feature. I need highlighting capability. I used free Bible apps, and they all seem to have that standard. If some could please help with that, it would me a great deal. Thank you.
