Editing the amount of scrolling with page up and page down

When I use page up and down I still always have the last red row
at the top of the new page. What have I to edit to increase the amount of Scrolling?

If you want page-by-page navigation, switch to single page view (Ctrl-6) and non-continuous view and use fit to page zoom (Ctrl+0).

Then page up / page down will move exactly by page.

In continuous mode we scroll exactly by visible area and because we have spacing between pages even if a page fits exactly to the window, after scrolling by the visible screen the spacing will cause an offset, which will accumulate.

You can set the spacing to 0 via Settings/Advanced Options (set PageSpacing = 0 0 in FixedPageUI section).

I changed the PageSpacing to 0 0 in FixedPageUI but still the same Problem.

I would have to see a screenshot and/or the file and know which view/zoom you use.

The above only works if PDF has pages of uniform size and you use the right zoom and view.

If any of the above is not true, it won't scroll perfectly by a page.

Its a normal pdf ebook with totally equal page size.
When I use page down to the next Screen page I always see the last sentence from the preview Screen page before.

I use continuous and fit to Screen width.

Looks like you're using "fit width" zoom. It has to be "fit page".
Krzysztof Kowalczyk on February 27, 2017
When I use "fit page" than I see the complete page very small and I can jump from a complete page to the next complete page without overlap. But this is helpless for me because I am only using one thierd of the Screen width. What I want is using the complete Screen width and vertical Scrolling with pageUp and
pageDown without Line overlap. This works in Acrobat Reader.
Randy R. on February 27, 2017
I will use the complete width of the Screen. I know that I only can see the complete width of my page but not the complete length. This is no Problem for me because I can press the pageup
and pagedown keys to get Forward and backward in the document. When I go Forward to the next Screen I see always the last line again from my Screen before and that is very irritating. The amount of Scrolling must be about 1 line more. Something with your formula in fit width is not working. When I use pageup and pagedown in this Modus its not Scrolling a complete page high, its about 10 to 15 mm less.
Randy R. on February 27, 2017
Its like you read a book, finish page, turn the page and see the last sentence again.
Randy R. on February 27, 2017
I am a simple pdf reader. But with the issue above I can get no satisfaction. It should be possible in screem width continious mode to use pageup and pagedown keys without line overlap. Because of this is a basic Funktion I need I go back to Acrobat Reader. I think Krzystof did not understand my Problem, sorry.
