+Many TeX programmers provide more or less detailed manuals for
+their programs or packages. They are usually available as .dvi,
+.ps, .pdf, .html or plain text files (sometimes included in the
+.sty files instead of a separate documentation file) and can be
+accessed with this browser, which is simply an interface to find a
+documentation more easily. It starts the respective viewer for
+reading the selected documentation making use of a database file
+which contains the path entries according to the current teTeX
+texmf/doc structure; additional usage of a system-wide local and
+of individual user texmf trees with corresponding databases is also
+possible.
+The documentations are grouped in several categories shown in the
+main window; pressing one of its buttons lists all documentations
+belonging to this topic.
+The topic window lets you select one documentation file, view or
+send it to the default printer. By right-clicking on the selected
+item you get the complete path of the file.
+The search button of the main window allows you to search the
+database for a string; it does not search file names. Enter the
+string and hit <Return> to start the search or <Control-c> to
+cancel. Just hitting <Return> without typing something in will
+show the full list of files in the database.
+Defaults for the documentation root directory, the viewers, the
+converters, certain options and the printer are set in the global
+configuration file $sysrc.
+However, each user can put a copy of it as .texdocrc into his home
+directory to modify them according to his needs; modification or
+generation of ~/.texdocrc can also be done with the Settings menu.
+Additionally, the settings can be changed temporarily with this
+menu.
+
+The following key shortcuts are defined for use with the browser:
+ <Ctrl-q> Quit browser
+ <Ctrl-m> Raise the Main window to the foreground
+ <Ctrl-s> Search a keyword in database (case insensitive)
+ <Ctrl-c> Cancel/close subwindow or search entry widget
+ <Ctrl-v> View selected document (topic windows)
+ <Ctrl-p> Print selected document (topic windows)
+ <Ctrl-t> Open settings menu
+ <Ctrl-k> Kill fatal error message window (same as
+ <Ctrl-q>)
+ <Ctrl-h> Open this help
+ <Return> Equivalent to button press;
+ OK in selection menu and search
+ <Tab> Next/previous widget
+
+There are the following command line options:
+ -a autostart viewer if a listbox of search results
+ contains only one item; can also be set in a
+ configuration file
+ -v disable suppression of viewer messages sent to
+ stderr and of certain permanent message popup
+ windows, in case this was not set in a
+ configuration file; default: off
+
+Some more information is available in the manpage of texdoctk.
