More standard actions for Styled Text areas

You want to quickly create a toolbar for your Styled text areas. You want to change the font of the text or compute/freeze 4D Expressions without writing a line of code. It is possible using the new standard actions for Styled Text areas.

Just associate a standard action to each button object and 4D will handle everything automatically: action triggering but also the button activation or deactivation if the action is not available in the current context.
