Rich Text Notes Toolbar [Enterprise Architect User Guide]

Although it is not an independent toolbar that you can pin to the screen top or sides, or float in your work area, the Rich Text Notes toolbar appears in many places across Enterprise Architect in the Notes and Description fields of:

The element Properties dialog:

General tab
Requirements tab
Scenario tab
Hyperlink Notes

The Diagram Properties dialog
The Connector Properties dialog
The Message Properties dialog
The Operations and Attributes Properties dialogs
The Testing Window descriptions
The Notes window
The Rules and Scenarios Window for:

Requirements
Linked Requirements
Scenarios.

Notes:

If the toolbar is displayed but grayed out, the text field is read-only and cannot be edited. Other Description or Notes fields in Enterprise Architect might not have the toolbar, in which case the Rich Text Notes facility is not available for those fields.
For any Notes text that is displayed on a diagram, you must select the Render Formatted Notes checkbox on the Feature Visibility dialog in order to reproduce the formatting.

The options of this toolbar operate on selected text and any new text continuing from the formatting. The options (with some keyboard shortcuts) are, from left to right:

Make text bold [Ctrl]+[B]
Make text italic [Ctrl]+[I]
Underline text [Ctrl]+[U]
Change the font color of the text
Insert list bullet points [Ctrl]+[.] (full stop)
Insert list numbering [Ctrl]+[1]
Make text superscript
Make text subscript

Additional keyboard shortcuts:

Undo changes [Ctrl]+[Z]
Redo changes [Ctrl]+[Y] or [Ctrl]+[Shift]+[Z]
Copy [Ctrl]+[C]
Paste [Ctrl]+[V]
Cut [Ctrl]+[X]

Any Note text appearing in the element Note compartments in diagrams is not formatted.
