  <para>
    This section of the manual describes the use of the menubar and
    the menus themselves. It then explains each entry in every
    &gnum; menu, submenu or context menu.

    <title>Using Menus</title>    

  <para>
    A menu is a graphical element within a program which appears with
    a list of options. For instance, almost all applications have a
    <guimenu>File</guimenu> menu through which the user can access the
    computer's filesystem to open or save their work. The main menus
    are on the menubar. The use of these menus is discussed in <xref
    linkend="menu-bars" />.
  </para>

  <para>
    &gnum; also uses context menus to
    give users a quick way to access certain commands. The context
    menu will open up right under the mouse pointer when one of the
    secondary mouse buttons, usually the rightmost, is clicked. This
    menu is called a context menu because the entries in the menu are
    different depending on the location of the mouse pointer. The
    <guilabel>context</guilabel> menus are discussed in <xref
    linkend="context-menu" />.
  </para>

  <para>
    Both the main menus, on the menubar, and context menus may have
    submenus. A submenu is indicated by a small right-pointing
    arrow. To access a submenu, move the pointer
    down to the submenu entry. When the submenu opens, 
    move the pointer directly across into the submenu.
    When there is not enough room to the right
    of the currently open menu, submenus may open to the
    left. Note that the submenu will
    close if the mouse pointer moves into any other menu entry.
  </para>

  <para>
    You can also use the keyboard to navigate menus and submenus.
    See <xref linkend="menu-bars" /> to access the main menus using the keyboard.
    Once a menu is displayed, menu entries can be highlighted by pressing the
    down and up arrow keys. When a submenu opens, pressing the right
    arrow key moves the highlight to the first entry of the submenu. When
    a submenu entry is highlighted, pressing the left arrow key removes
    the highlight from the submenu. Pressing the space bar or the <keycap>Enter</keycap>
    key activates the highlighted menu entry.
  </para>

  <para>
    Menu entries ending with an ellipsis (three dots) open a dialog window which
    asks for more choices.
  </para>
  </sect2>

  <sect2 id="menu-bars">
    <title>Menubar</title>    

    <para>
      The default location of the menubar is at the top of the
      application window.  The menus provide quick and organized access
      to all major commands such as opening files, saving files,
      printing and quitting the application.

    <para>
      To open a &gnum; menu, click on the name of the menu in the menu bar.
      Once clicked, the menu will stay open.
      If the mouse pointer is moved to the name of another menu on the
      menubar, the first menu will close and the new menu open up. This is a useful way
      to look in each menu to hunt for a commands. Menus can also be
      opened through the keyboard.
      Pressing and holding the <keycap>Alt</keycap> key causes 
      one of the letters in each menu name to be underlined.
      Press-and-hold <keycap>Alt</keycap> and press the underlined letter
      to open the associated menu.
      Using the keyboard for menu activation or navigation causes
      a letter of each menu or submenu item label to be underlined.
      Press that letter key to activate the menu item.
      Once a menu is open, the arrow keys can be used to move between
      menus or select an entry in a particular menu.
      To close an open menu, click over any other area of the application
      or of the desktop or press the Escape key, <keysym>Esc</keysym>.
    </para>

    <para>
      Many menu entries are followed by a series of key names. These
      keys can be used to perform the menu action without having to
      open the menu.  These are often combinations of keys involving
      the control key which is labeled as <keycap>Ctrl</keycap>, the
      shift key which is labeled <keycap>Shift</keycap> and the
      function keys which are labeled with an <keycap>F</keycap> and
      then a number. For example, to quickly cut a selection
      (accessible through the <guimenu>Edit</guimenu> menu), the user
      can make a selection and then type the control key and the "x"
      key at the same time.

    <title>File Menu</title>

    <para>
      The <guimenu>File</guimenu> menu is the most important menu in
      &gnum; because it gives the user
      the ability to interact with the computer operating system. This
      menu allows the user to create files containing all the work
      they have done. It also enables users to print the results of
      their work. Finally, the <guimenu>File</guimenu> menu is the
      best way to close &gnum;.

                Rather than creating a new empty workbook, the template 
                specifies some standard content. The new workbook is opened in a new
                window. The name named of the workbook is determined by the name
                of the template. Note that the opened file has not yet

	<para>
	  These menu items allow the user to remove recent changes to
	  a worksheet or re-introduce changes which have been
	  undone. These options give the user control over recent
	  edits. This functionality is often called the "change
	  history" of an application. </para>
	
	<para>
	  The type of edit has no importance. An edit which deletes
	  the contents of a cell is treated in the same way as an edit
	  which adds contents to a cell. The change history is session
	  specific. The user will not be able to undo changes through
	  the change history if the file is saved and then
	  re-opened. Note also that the list only covers the last few
	  dozen operations. The number of operations which &gnum;
	  tracks in its history depends on the size and complexity of
	  those operations. You can customize this number using the preference
	  facility described in <xref linkend="chapter-configuring" />. 
	  There are a few unusual operations which

	      remove the last few edits from a workbook. The edits
	      must be undone in order. This menu item removes only the
	      last edit from the workbook. The user can also access

	These menu items enable selected cell contents to be moved
	around a spreadsheet, moved between worksheets or between
	workbooks. Selections are areas of the spreadsheet that have
	been chosen, usually with the mouse, and are usually colored
	pale blue. Selections are explained in greater detail in <xref
	linkend="sect-data-selections" />.
	&gnum; currently only allows
	single range selections for these operations.
	</para>

	<para>
	  To use these menu items, the user must first select the range
	  of the cut or copy area. When the user then picks these
	  menu items, the contents of the selected areas will be
	  entered into the &gnum;
	  clipboard and into the X clipboard. The
	  contents of the &gnum;
	  clipboard can then be inserted into a new region of the
	  spreadsheet, into another worksheet or into a new
	  workbook. The X clipboard holds the space delimited results
	  of each cell: either the text or the result of any
	  calculation. The X clipboard can be pasted into any text
	  area.

	      <guimenuitem>Cut</guimenuitem> &mdash; The
	      <guimenuitem>Cut</guimenuitem> menu item is used to
	      remove a selection from the selected area of a currently
	      open workbook. When the menu item is chosen, the
	      selected area will be outlined with a moving dotted
	      line. This is the area which will be moved. The
	      selection will only be removed after it is moved to the
	      new location. Until then cut has not had an effect on
	      the worksheet.

	      <guimenuitem>Copy</guimenuitem> &mdash; The

	      to duplicate a selection. The original data remains
	      where it was and the &gnum;

	      paste the contents of a selection which has been cut or
	      copied. If the selection was cut, it is pasted into the
	      new location unchanged. Cell references will not change
	      in that they will still point to the same cells.

	      three categories. The defaults make <guimenuitem>Paste

	    <para>
	      The first set of choices allow the user to control the
	      data pasted.The user can chose to limit the pasting to
	      only the cell contents (no cell formatting is copied) or ---
	      the opposite --- only cell formats copied (no
	      contents). Furthermore, the user can insert the
	      selection while transforming all the contents into
	      values only. In this case, formulae will not be copied, only the
	      results will be.
	    </para>
	    <para>
	      A second set of choices allows the user to perform
	      simple mathematical transformations during the
	      paste. The data in the cells being pasted into are
	      modified by the cell contents. For instance, using the
	      divide operation will result in each cell in the zone
	      pasted into being divided by the equivalent cell which
	      was copied originally.
	    </para>
	    <para>
	      The third set of choices allow the transposition or flip of the
	      original selection. The
	      <guilabel>transpose</guilabel> choice will change the
	      selection by flipping it about the diagonal from top left to 
	      bottom right. Similarly, <guilabel>flip horizontally</guilabel> and 
	      <guilabel>flip vertically</guilabel> paste the selection accordingly.
	    </para>
	    <para>The <guilabel>skip
	      blanks</guilabel> check box prevents
	      &gnum; from taking any
	      action for the cells in the selection that are
	      blank. Normally &gnum; will modify formulae that use relative 
	      addressing to cells outside the selection. The <guilabel>do not
	      change formulae</guilabel> checkbox suppresses this change. (Note that 
	      references to cells within the selection are always preserved.)

                row 12, the user could select row 13 and select this

	   data. The template will not affect data which has already
	   been input into a worksheet.

	   <guilabel>Settings</guilabel> menu, an
	   <guilabel>Edit</guilabel> menu and a category chooser. The
	   settings menu allows a user to pick what parts of the
	   template they want to copy into the worksheet. The edit
	   menu will be used to create new templates. Currently
	   templates are written as text into an extensible markup
	   language (XML) format. The category chooser gives the user
	   access to different groups of templates.  Templates in each
	   category are displayed in the middle area of the
	   dialog. Users select the template they want to use by
	   clicking on it.  The currently selected template is
	   highlighted with a red boundary which may be hard to see.

		to calculate on the basis of the cells in several
		columns.  &gnum; can sort
		a selection using any number of rules. Rules can be
		added using the <guibutton>Add</guibutton>

<!-- TODO: add info area context menu. -->
<!-- TODO: add text entry context menu. -->

	<para>Context menus are menus which open up under the mouse pointer and are
	therefore detached from the format graphical structure
	of the application. These menus provide an extra and convenient way to access
	&gnum; commands. All of the commands in context menus are available
	through the regular menu system. Context menus provide different commands
	depending on the position of the pointer.</para>

	<para>To activate a context menu, a user simply positions the pointer over
	the appropriate area and clicks one of the buttons on their mouse. Since this
	button is configurable and users have mice with different buttons, it may be a
	different button on any given machine or may even require the combination of a
	keyboard key and a mouse buttons. The user will have to find how to do this
	themselves.</para>

  <para>
    Currently &gnum; provides five different context menus. The
    context menu that is called in the central grid area is discussed
    next in <xref linkend="menu-context-grid" />. The Context menu
    that appears when the pointer is over the row headers or column
    headers is presented in <xref
    linkend="menu-context-col-row-header" />. Another context menu
    relates to the worksheet tabs and is explained in <xref
    linkend="menu-context-tabs" />. Yet another context menu applies
    to embedded objects or shaped components such as a plot. These are
    shown in <xref linkend="menu-context-object" />.

      mouse pointer over the element and clicking with one of the
      secondary mouse buttons.
    </para>

    <para>
      The first menu entry, labeled
      <guimenuitem>Properties</guimenuitem>, will open a dialog
      specific to the type of element selected in which the user can
      configure the properties of the element.
    </para>

    <para>
      The menu entry labeled
      <guimenuitem>Size &amp; Position</guimenuitem>, will open a dialog
      that permits the user to adjust the size and position of the embedded object.
    </para>

    <para>
      The menu entry labeled
      <guimenuitem>Snap to Grid</guimenuitem>, enlarges the object such that all of
        its corners are located at cell corners.
    </para>

    <para>
      The menu entry labeled <guimenuitem>Order</guimenuitem>,
      opens a submenu which allows the user to change the visual order
      in which the graphical elements are placed. This order will
      affect the way in which the graphical elements obscure each other.

      The menu entries labeled <guimenuitem>Cut</guimenuitem>,
      <guimenuitem>Copy</guimenuitem>, and
      <guimenuitem>Delete</guimenuitem>, allow the user to operate on
      the whole object at once. The <guimenuitem>Cut</guimenuitem>
      menu item allows the user to remove the element from its current
      position and then paste the object in a different location on
      the same sheet, in a different worksheet, in a different
      &gnum; file, or in a file from a different program entirely. The
      <guimenuitem>Copy</guimenuitem> menu item provides the same
      functionality while leaving the original item in place. The
      <guimenuitem>Delete</guimenuitem> allows the user to remove the
      graphical element entirely.

    <para>
      The remaining menu item, <guimenuitem>Print</guimenuitem>, allows just the
      selected object to be printed.

      For certain types of objects, a menu entry labeled <guimenuitem>Save

      allows the object to be saved as an image file. This menu item

	  The context menu for toolbars allows the user to configure toolbars.
	  Each toolbar can be displayed above the sheets, to the left of the sheets,
	  or to the right of the sheets. The context menu can also be used to hide a
	  toolbar. The toolbar can be made visible again via the
	  <guimenuitem>Toolbars</guimenuitem> submenu of the <guimenu>View</guimenu>
	  menu. See <xref linkend="View-Menu"/>.
