9	With snapshots, you can save a particular state of a virtual
10	machine for later use. At any later time, you can revert to that
11	state, even though you may have changed the VM considerably since
12	then. A snapshot of a virtual machine is thus similar to a machine
13	in Saved state, but there can be many of them, and these saved
14	states are preserved.
15	</p>
16	<p>
17	To see the snapshots of a virtual machine, click on the machine
18	name in VirtualBox Manager. In the machine tools menu for the VM, click
19	<b outputclass="bold">Snapshots</b>. The Snapshots tool is
20	displayed.

27	If you select multiple VMs in the machine list, all snapshots are
28	listed for each VM.
29	</p>
30	<p>
31	Until you take a snapshot of the virtual machine, the list of
32	snapshots will be empty, except for the
33	<b outputclass="bold">Current State</b> item. This item
34	represents the current point in the lifetime of the virtual
35	machine.
36	</p>
37	<p>
38	The Snapshots window includes a toolbar, enabling you to perform
39	the following snapshot operations:
40	</p>
41	<ul>

43	<p>
44	<b outputclass="bold">Take.</b> Takes a snapshot of the
