How can I edit the scroll length when I press the spacebar?

Hello. I like to read PDF's by using the spacebar to scroll down. Hoever, I have an issue. I want the PDF to scroll down BUT leave one or two lines (or pixels or percentage of the page) still on screen when I scroll down. As it is, it scrolls down almost 100% percent, but sometimes I need just that 1 extra line for context. How can I decrease the movement caused by the spacebar?

The space bar is essentially giving you your next screen full of info, so the amount you progress with each press is entirely dependant on your magnification.  Also, the behaviour changes a bit if your view settings are set to continuous scrolling vs. single page view,  If a different magnification gives you the behavior you want, I'd set that as the initial page view magnification in Document Properties.

I hope this is helpful info.
