When you press CTRL+S, the bookmarks are saved.
Alternatively, just try to close dview by pressing ESCAPE -
the tool will ask automatically if bookmarks should be saved.
The bookmark filename is based on what you loaded,
and how you loaded it. As a general rule,
- you OPEN the directory
C:\mydocs\letters
then the bookmark filename is
C:\mydocs\zz-letters-bookmarks.1.dvbm
so the bookmarks are parallel to that directory.
- after that, you APPEND the directory
C:\otherdocs\diverse
but the bookmark filename STILL is
C:\mydocs\zz-letters-bookmarks.1.dvbm
as only OPEN redefines the bookmark path.
- you OPEN the single file
C:\mydocs\letters\hello.txt
then the bookmark filename is
C:\mydocs\letters\hello.txt.1.dvbm
so the bookmarks are parallel to exactly that file.
- if you specified multiple directories to load text from,
esp. during start from the command line,
the first of those directories is taken to build
the bookmark filename.
- if you load a single file, the bookmark filename
is based on that filename.
