+{This window is a text widget.  It displays one or more lines of text
+and allows you to edit the text.  Here is a summary of the things you
+can do to a text widget:
+
+1. Scrolling. Use the scrollbar to adjust the view in the text window.
+
+2. Scanning. Press the middle mouse button in the text window and drag up
+or down. This will drag the text at high speed to allow you to scan its
+contents.
+
+3. Insert text. Press mouse button 1 to set the insertion cursor, then
+type text.  What you type will be added to the widget.
+
+4. Select. Press mouse button 1 and drag to select a range of characters.
+Once you've released the button, you can adjust the selection by pressing
+button 1 with the shift key down.  This will reset the end of the
+selection nearest the mouse cursor and you can drag that end of the
+selection by dragging the mouse before releasing the mouse button.
+You can double-click to select whole words or triple-click to select
+whole lines.
+
+5. Delete and replace. To delete text, select the characters you'd like
+to delete and type Backspace or Delete.  Alternatively, you can type new
+text, in which case it will replace the selected text.
+
+6. Copy the selection. To copy the selection into this window, select
+what you want to copy (either here or in another application), then
+click the middle mouse button to copy the selection to the point of the
+mouse cursor.
+
+7. Edit.  Text widgets support the standard Motif editing characters
+plus many Emacs editing characters.  Backspace and Control-h erase the
+character to the left of the insertion cursor.  Delete and Control-d
+erase the character to the right of the insertion cursor.  Meta-backspace
+deletes the word to the left of the insertion cursor, and Meta-d deletes
+the word to the right of the insertion cursor.  Control-k deletes from
+the insertion cursor to the end of the line, or it deletes the newline
+character if that is the only thing left on the line.  Control-o opens
+a new line by inserting a newline character to the right of the insertion
+cursor.  Control-t transposes the two characters on either side of the
+insertion cursor.  Control-z undoes the last editing action performed,
+and }
+
+switch [tk windowingsystem] {
+    "aqua" - "x11" {
+	$w.text insert end "Control-Shift-z"
+    }
+    "win32" {
+	$w.text insert end "Control-y"
+    }
+}
+
+$w.text insert end { redoes undone edits.
+
+7. Resize the window.  This widget has been configured with the "setGrid"
+option on, so that if you resize the window it will always resize to an
+even number of characters high and wide.  Also, if you make the window
+narrow you can see that long lines automatically wrap around onto
+additional lines so that all the information is always visible.}
