[Feature request] Add "focus mode" option to emphasize a subsection of text?
Motivation
One of the major bottlenecks I've currently noticed when working with Zathura for PDF reading, is that it's very easy for me to lose my place.
When taking notes, for instance, I will often jump back-and-forth between reading in Zathura, and writing some notes in Neovim.
Even when the windows are tiled & displayed side-by-side, however, I find that I often have to take a few moments each time I shift my focus back to Zathura, in order to figure out where I had left off.
Possible solution
One possible solution that could help with this, would be to implement support for enabling sentence/paragraph// "emphasis", which can then be controlled & moved by the user, e.g. using arrow keys to slide it's position 1 unit forward/backward.
For example, the current text block that is in focus could be rendered normally, and all of the surrounding text could be dimmed.
Alternatively, the focus text could be highlighted, and the outside text could remain as-is.

Just a thought..
Thanks for all of your work on Zathura! It is really wonderful and I use it every day.
