+  <para>
+    Each cell in a worksheet can have an associated comment.
+    Comments are not ordinarily visible.
+    Cells having associated comments are marked with a red triangle
+    in the top right corner of the cell.
+    If you move the mouse cursor over the red triangle, the cursor
+    changes to the left-pointing arrow.
+    If the cursor remains over the triangle long enough, a pop-up
+    window appears, displaying the author's name and the text of
+    the comment.
+    The pop-up window is removed when the mouse cursor is moved off
+    the red triangle.
+  </para>
 
+  <para>
+    To add a comment to a cell, first select the cell.
+    Next choose <guimenuitem>Comment...</guimenuitem> from the
+    <xref linkend="Insert-Menu" /> to open the <guimenu>New Cell Comment</guimenu> dialog.
+    If the cell already has an associated comment, &gnum; instead opens the
+    <guimenu>Edit Cell Comment</guimenu> dialog, which is shown below. The
+    only difference is that the <guimenu>Edit Cell Comment</guimenu> dialog
+    is initialized with the existing comment and it includes a line identifying
+    the author of the existing comment.

+  <para>
+    To change the appearance of the comment text, select the
+    text to be formatted, then click on one of the character
+    attribute selectors above the comment text box. You can
+    select italics, strike-through, character weight, and
+    underlining. The italics and strike-through selectors toggle the
+    character attributes, based on the first character of the
+    selected text. For example, if the first character is
+    italic, clicking on the italics selector removes the italic
+    attribute from all characters of the selected text.
+  </para>
+  <para>
+    The arrows next to the weight and underlining
+    selectors open menus from which you can select a
+    weight or underline style.
+    Selecting a weight or underline style applies it to
+    the selected text and makes it the meaning of the
+    associated selector. For example, if you select
+    <guimenuitem>Light</guimenuitem> from the weight menu,
+    the selected text is made light. If you subsequently
+    click on the weight selector, the text selected at that
+    time is also made light.
+    The weights may not all be visibly different,
+    depending on the font in use. 
+  </para>

+    "Wrap in properties window" controls word wrap in the comment
+    editing box just above it.
+    By default, lines are broken at spaces between words to prevent
+    a line from exceeding the width of the text box.
+    Click on the check-box to toggle word wrap.
+    Line breaks occur in the comment pop-up only where you place
+    them explicitly by pressing <keycap>Enter</keycap>.
+    Turning off word wrap lets you see how the comment will be displayed
+    in the pop-up.

+  <para>
+    Names are labels with a meaning defined in the spreadsheet or by &gnum;.
+    Names can be defined for a whole workbook or for just a single worksheet.
+    A name can refer to a numeric value, a string, a range of cells, or a formula.
+    A name can be used wherever its meaning could otherwise be used.
+  </para>
+  <para>
+    A name is a sequence of letters, digits, and underscore characters,
+    beginning with a letter or underscore.

+    corresponding to the workbook, the active sheet, and the inactive
+    sheets, if any. When the dialog is opened, only the names defined
+    for the workbook and the active sheet are visible; the definitions
+    for any inactive sheets are collapsed into a single line for each,
+    identified by the sheet name. The definitions for the workbook or
+    a sheet can be exposed or hidden by clicking on the arrow at the
+    left end of the workbook or sheet line.
+  </para>
+  <para>
+    The second column of the <guimenu>Define Names</guimenu> dialog can 
+    show one of three icons. To define a new name, click on the
+    plus sign in the row for the workbook or the active worksheet.
+    Names defined under a worksheet name are visible
+    only on that worksheet.
+    Names defined for the workbook are visible to any
+    worksheet that does not have its own definition of the name.
+    Names are created as "&lt;new-name&gt;", which must be changed
+    before the definition can be used. Click on the new line to select
+    it, then click on the name field and type the new name, followed by
+    the <keycap>Enter</keycap> key.
+    When you press <keycap>Enter</keycap>, the name is fixed.
+    Only its value can then be changed.
+  </para>
+  <para>
+    If the second column shows a minus sign, the line is for a
+    user-defined name. 
+    Click on the minus sign to delete the definition of the name.
+    If the second column shows a padlock icon, the definition is created 
+    automatically and cannot be modified from this dialog.
+  </para>
+  <para>
+    For user-defined names, the third column of the <guimenu>Define
+    Names</guimenu> dialog contains a downward- or upward-pointing arrow.
+    Click on the arrow to move the definition down to the worksheet or
+    up to the workbook.
+    This operation is not permitted if the moved definition would replace
+    a name already defined for the destination.
+    To do such a replacement, first delete the name in the destination,
+    then move the definition.
+  </para>
+  <para>
+    The last column of the dialog shows the value defined for the name. 
+    When a new name is created, this field is initialized with an absolute 
+    reference to the currently selected cells.
+    To modify a definition, click on the value field and edit it as
+    desired, then press the <keycap>Enter</keycap> key.
+    To define a string value, enclose it in quotation marks, for example,
+    'string one' or "string two".
+    To specify a range of cells, use absolute references.
+    Relative references change in meaning depending on the cell where
+    they are used, which is unlikely to produce your intended result.
+    You can define a name as a cell or range of cells by clearing its
+    existing definition, if any, and then selecting the desired cell or
+    cells on the cell grid.
+    You can switch worksheets prior to selecting cells.
+    The dialog continues to modify names defined for the workbook or the
+    worksheet that was displayed when the dialog was opened.
+    A reference created by selection in the <guimenu>Define Names</guimenu>
+    dialog includes the worksheet name and uses absolute cell coordinates.
+    That is, a selection would look like "Sheet1!$A$1:$B$24".
+  </para>
+  <para>
+    Below the display of defined names is a filter box.
+    If the workbook or sheet contains many defined names, you can see
+    a subset of the names by typing a partial name in the filter box
+    and pressing <keycap>Enter</keycap>.
+    All names that do not contain the entered string are omitted from the
+    display.
+    Differences of case are ignored.
+    For example, if &ldquo;real&rdquo; were entered in the filter box,
+    names such as "Real_Value" and "Surreal" would be displayed.
+    When you press <keycap>Enter</keycap> in the filter box, contexts that contain
+    no matching names are automatically collapsed. You may later need 
+    to manually expand the workbook line, for example, if the filter
+    string is changed.
+    If the line for the workbook or a worksheet begins with a
+    right-pointing arrow, it contains names that pass the filter.
+    Clicking on the arrow will change it to a downward-pointing arrow
+    and make the names visible.
+    To see all the defined names, clear the filter by clicking on the
+    button at the right end of the filter box.
+  </para>
