  <tmdoc-title|Inserting new objects>

  After insertion of a new picture or clicking inside an existing picture,
  the second mode dependent toolbar shows a<nbsp>list of icons which are
  useful in graphics mode. In particular, the second group of icons
  <icon|tm_point_mode.xpm>, <icon|tm_line_mode.xpm>,
  <icon|tm_cline_mode.xpm>, <icon|tm_spline_mode.xpm>,
  <icon|tm_cspline_mode.xpm>, <icon|tm_arc_mode.xpm>,
  <icon|tm_carc_mode.xpm>, <icon|tm_textat_mode.xpm>, <icon|tm_math.xpm> on
  this toolbar allows you to select the kind of objects that you want to
  insert. <TeXmacs> currently implements the following primitive graphical
  objects:

  <\description>
    <item*|Points>When selecting point mode using <icon|tm_point_mode.xpm> or
    <menu|Insert|Point>, you may insert simple points with the left mouse
    button.

    <item*|Lines and polygons>When selecting line mode using
    <icon|tm_line_mode.xpm> or <menu|Insert|Line>, you may insert a new
    broken line with the left mouse button: at every new click a new point is
    inserted and the last point is inserted using a double click. Polygon
    mode (<icon|tm_cline_mode.xpm> or <menu|Insert|Polygon>) is a variant of
    line mode, with this difference that an additional segment is inserted
    between the first and the last points.

    <item*|Splines and closed splines>Spline mode is selected using
    <icon|tm_spline_mode.xpm> or <menu|Insert|Spline>. This mode is similar
    to line mode, except that we now draw a smooth curve through the
    specified points. Again, this mode admits a closed variant
    (<icon|tm_cspline_mode.xpm> or <menu|Insert|Closed spline>).

    <item*|Arcs and circles>Arc mode is selected using <icon|tm_arc_mode.xpm>
    or <menu|Insert|Arc>. In this mode, you may insert arcs going through
    three points specified through left mouse clicks. Similarly, you may use
    circle mode (<icon|tm_carc_mode.xpm> or <menu|Insert|Circle>) for drawing
    circles.

    <item*|Text and mathematics>When selecting text mode
    (<icon|tm_textat_mode.xpm> or <menu|Insert|Text>) or mathematics mode
    (<icon|tm_math.xpm> or <menu|Insert|Mathematics>), you may enter text (or
    mathematics) at an arbitrary position in the picture, again using the
    left mouse button.
