On a block diagram string constant, there are shortcut menus to change the display style. Currently, we can change the style without making the selector visible. That leads to bugs when later programmers do not realize that the string they are editing is in a different mode. Currently, we have to choose "Visible Items >> Display Style" first, which makes the shortcut menu items useless (because then we just use the now-visible selector ring). In the future, when we change the style through one of the shortcuts, I would prefer that the selector automatically becomes visible.
