 Dmuse is initially provided with wordwrap disabled.  You can activate it using a command from the {{keypress|F9}} menu.  When wordwrap is enabled, {{keypress|KeyPad *}} toggles it on and off.  When wordwrap is "on," you will see the wordwrap flag [W] on the right-hand side of the top frame.  We rarely work with wordwrap on, but we do use it to reformat (change the horizontal size of) paragraphs.

For these commands to work properly, all text must be to the left of the right margin.		The margins have meaning even when wordwrap is off.

Line highlighting commands

 === Line highlighting commands ===
-The second type of highlight is the line highlight.  To get the line highlight, hold down the {{keypress|Left-Shft}} key and use the {{keypress|PgDn}} or {{keypress|Down}} key.  {{keypress|Left-Shft}} used with {{keypress|PgUp}} or {{keypress|UP}} in this situation can be used to reduce the number of lines highlighted but not to start a line highlight.  With lines highlighted, you have the following options.
+The second type of highlight is the line highlight.
-# Use the Delete key to delete lines to the line buffer.
+<center>
-# Use the Insert key to copy lines to the line buffer.  Lines will not be deleted in this case.
+{| class="wikitable" cellpadding="5" cellspacing="0" border="1" style="width:700px"
-The line buffer does not work like the box buffer.  It is a last-in, first-out trash heap.  And its size is limited only by the size of your disk!  The command {{keypress|Shft|Alt|Insert}} will retrieve the last "block" of lines put the line buffer, whatever number of lines that was, and insert them into your current window just above the cursor.  The command {{keypress|Ctrl|Shft|Insert}} will do the same thing, but will copy instead of retrieve the lines from the line buffer.  You can use {{keypress|Ctrl|Shft|Insert}} multiple times to copy the same group over and over again.
+Note: We normally use the line highlight method to delete or copy lines. Not only does this allow groups of lines to be deleted/copied, but also for safety reasons it is helpful to <i>see</i> what you are deleting <i>before</i> it is deleted.  Note also that all lines deleted in this way can always be recovered at least once.  The trash heap never goes away, but the top layer can be removed.  There are two other commands that delete lines (covered below), which do not put deleted material on the trash heap.  Material delete by those commands goes away completely (from the window, anyway).

	The Dmuse interface makes extensive use of the keyboard with numerous combinations of the {{keypress\|Shft}}, {{keypress\|Ctrl}}, and {{keypress\|Alt}} keys. Since the layout and response for the PC-Linux and Macintosh keyboards is slightly different (<i>e.g.</i>, the Mac has no {{keypress\|Insert}} key), there are some differences between the PC-Linux and Macintosh versions of the command list. The Dmuse documentation is designed to take this into account; so that if you are running the Mac version of Dmuse, all of the internal documentation will correspond to that version. For purposes of this document, the following descriptions will be for the PC-Linux version of Dmuse. Every keystroke combination in the PC-Linux version has a corresponding keystroke combination for the Mac.
