Edo SZ is a nice font style that allows you to give a smudged, brush effect to any text string.
To install a font unzip the files you have downloaded, then put the font files (.ttf, .otf) into /Library/Fonts . Edo SZ font integrates quickly into your system and you can easily access the custom glyphs though any text editing application.
Mac OS X comes with pre installed font styles and Edo SZ will simply be added to your pre existent library. The process is managed through the Font Book application, where you can easily browse and preview your currently installed fonts.
