HREF: HREF allows you to reference an external script or exe file. Note that you DO NOT end the LINE with an explicit backslash-n; however, backslashes need to be doubled.
SCRIPT BODY: SCRIPT BODY allows you to EMBED a script DIRECTLY in the OSD file. Note that you must end LINES with an explicit backslash-n (except for the last line), and that other backslashes need to be doubled.
