 * In diagrams:
 
-** Add tools to create timeslices and snapshots on `OccurrenceUsage`, `ItemUsage`, and `PartUsage` graphical nodes.
-These tools use a selection dialog to either create a graphical node based on an existing timeslice or snapshot, or, if nothing is selected, create a default timeslice or snapshot `OccurrenceUsage` graphical node.
+** Add tools to create _timeslices_ and _snapshots_ on `OccurrenceUsage`, `ItemUsage`, and `PartUsage` graphical nodes.
+These tools use a selection dialog to either create a graphical node based on an existing _timeslice_ or _snapshot_, or, if nothing is selected, create a default _timeslice_ or _snapshot_ `OccurrenceUsage` graphical node.
 
 ** Improved support for `Stakeholder`.
 It is now possible to create new _stakeholders_ from `Requirement` and `Concern` graphical nodes, whether they are definitions or usages.
 Created stakeholders must reference an existing `PartUsage`.
 By default, stakeholders are represented as dedicated graphical nodes connected to their parent graphical node, but they can also be displayed in the `stakeholders` compartment.
