Selecting the page scrolling power with the spacebar, PgUp & PgDn keys

[koplenov]

Spacebar, PgUp & PgDn do not scroll to the full page, but to half of it

I use a laptop without a mouse and often use the keyboard to navigate the page.

Now when I press Spacebar, PgUp or PgDn, the page scrolls completely.

This is often not convenient because you lose context, rather than scrolling would be smoother.

I propose to put in the settings how much the page will scroll when these keys are pressed (per page, half a page, a third of a page)

What do you think about that?
