\subsection{Text Viewer}
This is a Viewer for text files with word wrap. Just open a .txt file to
display it. The text viewer features controls to handle various styles of text
formatting, has top{}-of{}-file and bottom{}-of{}-file buttons. You can view
files without a \fname{.txt} extension by using \emph{Open with} from the
\emph{Context Menu} (see \reference{ref:Contextmenu}).

\subsubsection{The Viewer's Menu}

\begin{description}
\item[Quit] Exits the plugin.
\item[Viewer Options]
    \begin{description}
    \item[Encoding]
    sets the codepage in the text viewer.
% ToDo: wrap some of the following settings into a \opt{lcd_bitmap} to exlude
% ones that don't work on charcell - as soon as the plugin itself does
    Available settings:
    \setting{UTF-8} (Unicode),
    \setting{BIG5} (Traditional Chinese),
    \setting{KSX-1001} (Korean),
    \setting{GB-2312} (Simple Chinese),
    \setting{SJIS} (Japanese),
    \setting{CP1250} (Central European),
    \setting{ISO-8859-2} (Latin Extended),
    \setting{ISO-8859-9} (Turkish),
    \setting{ISO-8859-6} (Arabic),
    \setting{ISO-8859-11} (Thai),
    \setting{CP1251} (Cyrillic),
    \setting{ISO-8859-8} (Hebrew),
    \setting{ISO-8859-7} (Greek),
    \setting{ISO-8859-1} (Latin 1).
    This setting only applies to the plugin and is independent from the
    \setting{Default Codepage} setting (see \reference{ref:Defaultcodepage}).
    \item[Word Wrap] toggles between Wrap and Chop.
        \begin{description}
            \item[Off (Chop Words)] breaks lines at white space or hyphen.
            \item[On] breaks lines at the maximum column limit.
        \end{description}
    \item[Line Mode] cycles through Normal, Join and Expand and Reflow Lines.
        \begin{description}
            \opt{lcd_bitmap}{
            \item[Reflow Lines] justifies the text fully.
            }
            \item[Expand] adds a blank line. Useful for making the paragraphs
            clearer in some book style text files.
            \item[Join] joins lines. Useful for adopting the orphans that
            occur with e{}-mail style (i.e. pre{}-wrapped) text files.
            \item[Normal] breaks lines at newline characters.
        \end{description}
    \item[Wide View] toggles between Narrow and Wide.
        \begin{description}

            (Currently, Wide and Join cannot be selected together.)
            \item[No (Narrow)] sets maximum column to the screen width.
        \end{description}
    \opt{lcd_bitmap}{
    \item[Show Scrollbar] toggles scrollbar for the current View mode. If the
    file fits on one screen, there is no scrollbar and toggling this setting
    has no effect.
        \begin{description}
            \item[On] has a scrollbar by default, until toggled.
            \item[Off] has no scrollbar by default, until toggled.
        \end{description}
    \item[Overlap Pages] toggles between Normal and Overlap.
        \begin{description}
            \item[Yes] tells page{}-down/page{}-up to retain one line from previous screen.
            \item[No] sets page{}-down/page{}-up to one full screen.
        \end{description}
    }
    \item[Scroll Mode] controls the function of the ``Scroll-up'' and
    ``Scroll-down'' buttons.
        \begin{description}
            \item[Scroll by Line]
            \item[Scroll by Page]
        \end{description}
    \item[Auto-scroll Speed]
    controls the speed of auto-scrolling in number of lines per scroll step,
    available options are \setting{1} to \setting{10} lines. As an example,
    a setting of \setting{4} will scroll up the text four lines per second.
    \end{description}

\item[Show Playback Menu] controls the playback of the currently loaded playlist
and change the volume of your \dap{} without leaving the plugin.
\item[Return] to the text view.
\end{description}

\note{The text viewer automatically saves its settings and also stores the
current position in the viewed text files (up to the last 46 files).}
