The snapshot toolbar has two buttons, 'Snapshot' and 'Full Snapshot'. These buttons can be used while connected to a process to take a snapshot of the memory state at the current time.
Once a snapshot has been taken it will appear in the Snapshot list view in the side panel and as a red or yellow line in the graph view.
Snapshots can be selected by clicking on them in the side panel or in the graph view. A view
can be opened on a snapshot using the Snapshot Views toolbar buttons or right clicking in
the snapshot list view.
See Snapshot Views for more information.
