Where do I find a list of the macro variables that I can use in the footer and header controls in the "preferences" menu and "print" submenu has a pull down menu?  

The pull down menu offers "SHORT_Date" and time based on the date of printing, but I want to print out the for dates but by default uses current date for use in headers or footers - (e.g. "SHORT_Date") but the last modification date and time of the code files I am working on?

So does anyone know how to get modification date (preferably in short date format) and even also modification time in the printed header or footer?

Thanks…
