Line Height with the built in OSX Font Panel I am using an invoiving application, and would like to adjust some text properties including line height, but the only options available are show in the attached screenshot.  Does anyone have an idea how to adjust line height when the only tool you have is this font-chooser thingy (Is there a name for this)?



Thank you.
This is Fontbook. It is simply a font library, not where you manipulate fonts. You do not define font properties there:


  The Font Book application lets you install, remove, view, organize,
  validate, enable, and disable fonts. Fonts are styles of type that
  your computer uses to display and print text. OS X comes with many
  preinstalled fonts.


The programme you are using will (or will not) have the tools to format fonts. If your programme does not have this, you cannot set this in Fontbook.
