<p>You can control a kig construction by means of a "pykig"
python script, that can be executed with the command
<code>pykig.py</code>. Here is a nice example
(<code>hexagons.kpy</code>) you can try:
<code><pre>
kigdocument.hideobjects()
def hexagons (c, v, n):
hexagon = PolygonBCV (c, v, 6)
if n <= 0:
hexagon.show()
for i in range(6):
PolygonSide (hexagon, i, True)
return
cnew = MidPoints (c, v)
hexagons (cnew, v, n-1)
for k in [2,4]:
v1 = PolygonVertex (hexagon, k)
cnew = MidPoints (c, v1)
hexagons (cnew, v1, n-1)
hexagons (Point(0,0), Point(1,0), 5)
</pre></code>

<p>You can repeat the latest construction simply by pressing the key
'Z'; this comes in very handy if you need to construct a sequence
of objects with the same construction, especially if there is
no shortcut for that construction.</p>

<p>One of the most powerful tools in Kig are the menus that you can
enter by right-clicking on an object, or on some empty space in the
document. You can use them to give objects names, change their colors
and line styles, and lots of other interesting things.</p>

</tip>

<html>
<p>You can construct new points without using the menu or the toolbar, simply
clicking somewhere on the Kig document with the <em>middle mouse
button</em>.</p>

<p>Kig can open several file formats: its files (<code>.kig</code> files),
<em>KGeo</em> files, <em>KSeg</em> files, and, partially, <em>Dr. Geo</em>
and <em>Cabri™</em> files.</p>

<p>Kig has more than 20 objects and 10 transformations with more than 80
constructions you can use in your documents: open the <em>Objects</em>
menu to see them all.</p>
</html>
</tip>
<tip category="Kig">
<html>
<p>You can use the selected objects to start the construction of an object
which requires the selected objects as arguments. For example, if you have two
points selected, you can choose <em>Start->Circle by Three Points</em> from the
popup menu to start constructing a circle by three points.</p>

<p>Kig can extends its object set using external macros. You can find some
interesting macros on the Kig website:

<p>If you have more than one object under the mouse, and you want to select any
of them, you can click with the <em>left mouse button</em>, while holding the
<em>Shift</em> key, to get a list of the objects under the mouse cursor which
you can then select from.</p>

<p>When you construct a locus, you can click on it with the <em>right</em> mouse
button and select <em>cartesian equation</em> to see its cartesian equation,
whenever it is an algebraic curve of low degree.</p>
