I'm using Microsoft Visio to draw my UML Diagrams.
More specifically the "UML Class" package as shown below

I want to define my class as Abstract and I don't find any "Properties tab" or somth to manage any class options.
Is there any way to achieve this another way than simply set the class name as Italic in the text format option ?
EDIT
The solution provided here doesn't seem to fit with newer version of Visio as long as i can't find a "Properties" tab.
