Long time ago, Maxim Leyenson proposed some updates to the manual page.
Better documentation is very much needed, but I never got around into integrating the proposed text. :-/

NAME
djvusmooth is a GUI (Graphical User Interface)
DjVu file editor.
SYNOPSIS
djvusmooth [file]
DESCRIPTION
djvusmooth allows one to add (or edit) a table of contents (TOC)
of a DjVu document, and add or edit hyperlink within the document.
djvusmooth supports sub-bookmarks, and Unicode characters in the
bookmark names.
USAGE
When opening a DjVu file, three tabs appear on the left side of the
window, called "Outline", "Hyperlinks" and "Text".
The "Outline" section contains the table of contents (TOC) for the
DjVu file.
The section "Hyperlinks" contains page numbers for which hyperlinks
within the file have been created.
* Navigating the document
* Ctrl-g -- Go to a page with a given number
* PgUp, PgDown
* go to a specific bookmarked page:
choose a bookmark in the "Outline" section,
and press "Enter".
* Adding bookmark to a DjVu file
* go to a page you want to bookmark with Ctrl-G command,
or by navigating the document using PgUp and PgDown.
* Press Ctrl-B to bookmark the page. A new bookmark with the title
"(no title)" will appear on the left side of the screen under
the "Outline" tab.
* Rename the bookmark: click once with the left mouse button on
the current title ("no title"), edit the name, and press Enter.
* Reorganizing bookmarks in a DjVu file.
One can move around bookmarks under the "Outline" tag with a
mouse.
Also, see the discussion on moving bookmarks around here:
https://bitbucket.org/jwilk/djvusmooth/issue/1/
* Renaming bookmarks
Press once with the left mouse click on the bookmark title, edit
the name, and press Enter.
* Removing bookmarks.
Select a bookmark under the "Outline" tab and press the "Del"
keyoard button.
Warning: The "Edit-> Outline -> Remove" menu option removes the
outline (callection of all the bookmarks) on the DjVu file.
This can lead to a confusion when a specific bookmark is
selected, since in this case the command will remove all the
bookmarks as well, and not just the selected bookmark.
HYPERLINKS
* Adding a hyperlink inside a DjVu document.
Say, page #1 of the document has a table of contents (TOC) for
the document, which looks like
TOC page 1
Chapter 1 page 10
Chapter 2 page 20
....
and we want to add a hyperlink from the line "Chapter 2" to page
20 where the chapter 2 starts, so that when one mouse-clicks on a
line named "Chapter 2" in the TOC, one is redirected to the page
#20 in the document.
* Choose "Hyperlinks" tab in the left-side menu.
* Point the mouse on the line "Chapter 2" and right-click. A
pop-up "New Hyperlink" appears. Mouse-click on the words "New
Hyperlink"
* A new menu with hyperlink details appears.
Under the URI section, put "#20", so that the line "Chapter 2"
will be linked to the page #20 in the DjVu document.
* Border type: select "XOR" and "always visible"
(more variants are explained below).
* Press OK to create the hyperlink.
* Now, a small blue square is visible on the line
"Chapter 2". One can move it with mouse, and then left-click
on it to change the shape. Change the shape to create a
rectangle going around the line "Chapter 2", and left-click
on the rectangle again.
* Now, when one saves the file (Ctrl-S) and opens it again with
the DjView browser, a small grey rectangle is visible around
the line "Chapter 2". If one hovers over this line with a
mouse, DjView shows "Go: page 20" in the bottom of its window.
Left-clicking anywhere in the middle of this rectangle makes the
DjView go to the page #20 directly.
Other options: XOR, not selecting "always visible": the outline of
the hyperlink becomes visible only when mouse hovers over this
line.
