What do 3 buttons in eviewer do?

[phossler]

1. Looked in the manual, but didn't find answer

http://manual.calibre-ebook.com/viewer.html

2. There are 3 icons that don't appear to do anything, at least when I click. According to the tooltips they are

[Back], [Forward], and [Load a theme]

There is a [Next Page] and [Previous Page] which 'read' the book, so I can't figure what the [Back] and [Next] are supposed to do.

When I click [Load a theme] I thought I'd get a FileOpen dialog, but nothing happens

What is the purpose of the 3 buttons?


Thanks

@phossler - Back and Forward buttons are similar to same buttons in web browsers, navigate through browsing history - only active if there is any browsing history - ie you have viewed parts of the book in current session. Most useful if its a reference book that you navigate, non sequentially, via the ToC or via reference links etc.

I think you need to create and save some extra themes to get a list of themes. Themes are not saved as separate files, they are saved as entries in the viewer_themes.json file (config folder). Only one theme is shipped, in English it's labelled as default.
