Change font increment for WPF RichTextBox
I am using a WPF RichTextBox control to enter some user-formatted text, including setting the font size. The built-in commands for IncreaseFontSize and DecreaseFontSize will adjust the font size by 0.75pt each time the command is executed. I would like to increase the granularity to 2pt.
Can I do this without implementing my own custom commands?

Unfortunately the value is hardcoded and you cannot change it. The fastest way to do this is to use the TextRange class. Something like that:
var range = new TextRange( rtb.Document.ContentStart, rtb.Document.ContentEnd );
range.ApplyPropertyValue( TextElement.FontSizeProperty, 30.0 );
