The settings that are saved are the following: column count, layout, mask, margins, scroll mode, full screen mode, font replacement, line height, color scheme, color transform and hidden elements
. In addition, for pages and domains, the location of the selected element is saved, while for individual pages, the scroll location is saved.Scrolling.
The keys that can be used to scroll are the following: arrow left / arrow right / page up / page down / arrow up / arrow down / space / home
Reader areas that have a scroll function are recognizable by a custom mouse cursor. Content elements that can be scrolled horizontally show a horizontal arrow cursor.Tips

> In case content does not appear or cannot be read, your best option is to press the color scheme button.
> Left-click is disabled inside Column Reader
(except for internal links) for safety, but you may still use right-click.Known issues
