The Path tool allows to create complex selections called Bezier Curves,
a bit like Lasso but with all the adaptability of vectorial curves.
You can edit your curve, you can paint with your curve, or even save,
import, and export the curve. You can also use paths to create
geometrical figures. Paths have their own dialog box: Dialog/Paths.

You draw the path by clicking successively. You can move
control points by clicking on them and dragging them. Between
control points are segments.

Several functions are available with this mode:
</p>
<p>
<span class="emphasis"><em>Add a new node</em></span>: if the active node (a small
empty circle after clicking on a node) is at the end of the path,
the mouse pointer is a '+' sign and a new node is created, linked
to the previous one by a segment. If the active node is on the
path, the pointer is a square and you can create a new component
to the path. This new component is independant from the other, but
belongs to the path as you can see on the Path dialog. Pressing
<span><b class="keycap">Shift</b></span> forces the creation of a new component.
</p>
<p>
<span class="emphasis"><em>Move one or several nodes</em></span>: On a node, the
mouse pointer becomes a 4-arrows cross. You can click and drag it.
You can select several nodes by <span><b class="keycap">Shift</b></span> and click
and move them by click and drag.
Pressing <span><b class="keycap">Ctrl</b></span>-<span><b class="keycap">Alt</b></span>
allows to move all the path, as a selection.
</p>
<p>
<span class="emphasis"><em>Modify handles</em></span>: you have to Edit a node
before. A handle appears. Drag it to bend the curve.
Pressing <span><b class="keycap">Shift</b></span> toggles to symmetric handles.
</p>
<p>
<span class="emphasis"><em>Modify segment</em></span>: When you click on a segment,
the mouse pointer turns to a 4-arrows cross. Drag it to bend the
segment. As soon as you move, handles appear at both ends of the
segment. Pressing <span><b class="keycap">Shift</b></span> key toggles to symmetric
handles.
</p>
</dd>
<dt>
<span class="term">Edit Mode</span>
</dt>
<dd>
<p>
<span class="guilabel">Edit</span> performs functions which are not
available in <span class="guilabel">Design</span> mode. With this mode,
you can work only on the existing path. Outside, the pointer is
like a no-entry sign (on the whole image if there is no path!)
and you can do nothing.
</p>
<p>
<span class="emphasis"><em>Add a segment between two nodes</em></span>: Click on a
node at one end of the path to activate it. Pointer is like a
union symbol. Click on an other node to link both nodes. This is
useful when you have to link unclosed components.
</p>
<p>
<span class="emphasis"><em>Remove a segment from a path</em></span>: Pressing
<span><b class="keycap">Shift</b></span>-<span><b class="keycap">Ctrl</b></span>
key combination, point to a segment. Pointer turns to -. Click to
delete the segment.
</p>
<p>
<span class="emphasis"><em>Add a node to a path</em></span>: point to a segment.
Pointer turns to +. Click where you want to place the new control
point.
</p>
<p>
<span class="emphasis"><em>Remove a node</em></span>: Pressing
<span><b class="keycap">Shift</b></span>-<span><b class="keycap">Ctrl</b></span>
key combination, point to a node. Pointer turns to -. Click to
delete the node.
</p>
<p>
<span class="emphasis"><em>Add a handle to a node</em></span>: Point to a node.
Pointer turns to small hand. Drag the node: handle appears.
Pressing <span><b class="keycap">Shift</b></span> toggles to symmetric handles.
</p>
<p>
<span class="emphasis"><em>Remove a handle from a node</em></span>: Pressing
<span><b class="keycap">Shift</b></span>-<span><b class="keycap">Ctrl</b></span>
key combination, point to a handle. Pointer doesn't turn to the
expected - and remains a hand. Click to delete the handle.

<p> <span class="guilabel">Move</span> mode allows to move one or all

</p>
<p> If you have several components, only the selected
one is moved. If you click and drag outside the path, all
components are moved. Pressing <span><b class="keycap">Shift</b></span> key toggles
to move all components also. </p>
