<a id="select"><h3>SELECT OBJECTS</h3></a>
<p>
Objects can be selected by clicking the left mouse button when the pointer is very close to the object.
For rectangle objects the best point to select it is the internal side, close to one of the corners.
More objects can be selected by pressing the <kbd>Shift</kbd> key and clicking another object.
Once objects are selected they can be copied (<kbd>c</kbd> key), moved (<kbd>m</kbd> key), deleted
(<kbd>Delete</kbd> key) or attributes changed (<kbd>q</kbd> key).<br>
Objects can also be selected by area, by dragging with the left mouse button pressed a rectangle around the objects
you want to select.

<a id="resize"><h3>RESIZE OBJECTS</h3></a>
<p>
All Xschem base objects can be resized.
For lines, rectangles, polygons you need to drag the mouse with left button pressed and Ctrl key pressed
over one vertex/endpoint.
</p>

<p>
After releasing the mouse button the object will become selected
and a subsequent move operation (<kbd>m</kbd> key) will move the selected vertex/endpoint.
</p>

<p>
More objects can be rezized. You can add vertex/endpoints by pressing Ctrl and Shift and dragging the mouse
to enclose another vertex/endpoint. After selecting all desired elements pressing the <kbd>m</kbd> key
will resize all objects.
</p>

<p>
Circles can be resized as well. Capture the center of the circle with the above described mouse drag operation, the radius can be changed.
For arcs you can capture the center (to modify the radius) or the endpoints to change the start/end angle or the arc angle.
</p>
<h3>STRETCH OPERATIONS</h3>
<p>
An important operation that deserves a special paragraph is the <kbd>Stretch</kbd> operation.

<p>
Xschem can now display waveforms by itself in the drawing area. in the Simulation menu there is an entry to
add a graph: <kbd>Add waveform graph</kbd>. When this menu is pressed a box can be placed in the schematic:<br>

Xschem graphs are embedded into a rectangle object. Resizing graphs is done in the same way as resizing
a rectangle object. See the <a href="commands.html#resize">related page</a>.
To select a graph (to delete it or move it to a different position) click the left mouse button while in the area
shown in this picture:

The next step is loading the simulation data, This is done by menu
<kbd>Simulation-&gt;Load/Unload ngspice .raw file</kbd>. This command loads a .raw file produced by a ngspice/Xyce
simulation. The file name is expected to be <kbd>circuit.raw</kbd> where
