1 | \subsection{Text Viewer} | ||
2 | This is a Viewer for text files with word wrap. Just press PLAY on a | ||
3 | .txt file to display it. Has controls to handle various styles of text | ||
4 | formatting. Has top{}-of{}-file and bottom{}-of{}-file buttons. You | ||
5 | can view files without a .txt extension by using \textbf{Open with ..} | ||
6 | from the Play Screen menu | ||
7 | |||
8 | \subsubsection{Controls} | ||
9 | |||
10 | \begin{itemize} | ||
11 | \item \textbf{F1 (Recorder) / ON{}-MINUS (Player): } | ||
12 | toggles Word mode between Wrap and Chop: | ||
13 | |||
14 | \begin{itemize} | ||
15 | \item Wrap breaks lines at white space or hyphen. | ||
16 | \item Chop breaks lines at the maximum column limit. | ||
17 | \end{itemize} | ||
18 | |||
19 | \item \textbf{F2 (Recorder) / ON{}-MENU{}-PLUS (Player): } | ||
20 | cycles Line mode through Normal, Join and Expand: | ||
21 | |||
22 | \begin{itemize} | ||
23 | \item Normal breaks lines at newline characters. | ||
24 | \item Join ignores unpaired newline characters (i.e., joins lines). Useful for | ||
25 | adopting the orphans that occur with e{}-mail style (i.e.,pre{}-wrapped) text files. | ||
26 | \item Expand doubles unpaired newlines (i.e., adds a blank line). Useful | ||
27 | for making the paragraphs clearer in some book style text files. | ||
28 | \end{itemize} | ||
29 | |||
30 | \item \textbf{F3 (Recorder) / ON{}-PLUS (Player):} | ||
31 | toggles View mode between Narrow and Wide: | ||
32 | |||
33 | \begin{itemize} | ||
34 | \item Narrow sets maximum column to the screen width. | ||
35 | \item Wide sets maximum column to 114. Useful for navigating large | ||
36 | files. (Currently, Wide and Join cannot be selected together.) | ||
37 | \end{itemize} | ||
38 | |||
39 | \item \textbf{ON{}-F1 (Recorder):} | ||
40 | toggles Page mode between Normal and Overlap: | ||
41 | |||
42 | \begin{itemize} | ||
43 | \item Normal sets page{}-down/page{}-up to one full screen. | ||
44 | \item Overlap tells page{}-down/page{}-up to retain one line from | ||
45 | previous screen. | ||
46 | \end{itemize} | ||
47 | |||
48 | \item \textbf{ON{}-F3 (Recorder):} | ||
49 | toggles Scrollbar mode, for the current View mode. | ||
50 | |||
51 | \begin{itemize} | ||
52 | \item Narrow mode has no scrollbar by default, until toggled. | ||
53 | \item Wide mode has a scrollbar by default, until toggled. | ||
54 | \item If file fits on one screen, there is no scrollbar and ON{}-F3 has | ||
55 | no effect. | ||
56 | \end{itemize} | ||
57 | \end{itemize} | ||
58 | |||
59 | Settings are not remembered after the viewer has been exited. | ||

180 | \begin{itemize} | ||
181 | \item Correctly reads plain text files in Unix, Win/DOS, or Macintosh | ||
182 | format. Latin{}-alphabet Unicode files are a l m o s t r e a d a b l | ||
183 | e. | ||
184 | \item Currently prefers fixed{}-width fonts. With proportional fonts, | ||
185 | pretends all characters are the width of a lower{}-case 'o'. | ||
186 | \item Currently messages are in English | ||
187 | \item Does not currently support right{}-to{}-left languages. | ||
