<h1>5.5 GraphicSubgroupLattice, Selecting Vertices</h1><p>
<p>
Selected vertices are represented by a slightly thicker circle and, if
your screen supports color, are colored red.  There are five different
ways to select or deselect a vertex or a bunch of vertices.
<p>
Place the  pointer inside  a  vertex and press   the <strong>left</strong> mouse button.
Release   the button immediately   without  moving the  mouse.  This will
deselect all other vertices  and select this vertex.   If the vertex  was
already the only selected vertex it is deselected.
<p>
Place the  pointer inside a vertex, hold  down the <var>SHIFT</var> key, and press
the  <strong>left</strong> mouse button.   Release the button immediately without moving
the    mouse, release the   <var>SHIFT</var> key  afterwards.   If  the vertex was
deselected this action will  select it in  addition to any other selected
vertices. If the vertex was already selected it will be deselected.
<p>
Place the pointer  outside any vertex  and press the <strong>left</strong> mouse button.
Keep the button pressed and start moving the pointer.  This will create a
rubber band rectangle.  One corner at the position  where you pressed the
mouse button, the opposite corner following  the pointer.  As soon as you
release the left mouse button,   all  vertices inside the rectangle   are
selected, all vertices outside the rectangle are deselected.
<p>
Place the pointer outside any vertex, hold down the <var>SHIFT</var> key and press
the <strong>left</strong>  mouse button.  Again  you see a rubber  band, however, now as
soon as you release  the mouse button,  all vertices inside the rectangle
are selected in addition to any other selected vertices.
<p>
To select vertices from the <font face="Gill Sans,Helvetica,Arial">GAP</font> command window call the function
<code>SelectGroups</code> with a subgroup or a list of subgroups to select.
