Hi Ihor,

Glad you are interested. I have attached the screenshot showing how it is possible from within Org-mode! I concur on the need for font sizing and zooming the terminal at times. But for the most part I find it just works for various types of PDFs. I have filled multi-page documents but yes you will have to screenshot the pages separately. 

I am sure you will get the idea but please let me know if you require clarification. Hope this helps you like it does to me.
