After some searching -- it's not that obvious -- I found that the way to get
Seamonkey's, U-Light's and Firefox' scrollbar to scroll down the html page
page by page is to add the following to file < settings.ini > in directory
~/.config/.config/gtk-3.0:
Code: Select all
gtk-primary-button-warps-slider = false
when the page scrolls down to the same proportion of the page as your
cursor is on the scrollbar. E.g., you put your cursor ¾ down the scrollbar
and click, and the page goes down to the last quarter of the page. If you
want to read what's in between, you have to scroll back up. Of course,
the scrollbar provoked the same "warp" behavior on the page going
backwards.
With the modified GTK-3.0 setting, if you put your cursor ¾ down the
page and click, the html page will get there, but step by step, so you can
read the text between the top of the page and the last quarter of the
page. It doesn't just "jump" there. Of course, now it does the same
progressive step-by-step motion when you click up the scrollbar, too.
(Phew.)
