Print & Send in NAV 2013

Hi, Gang!

Does anyone know whether the "Print & Send" functions that are accessible from the upper-left "Drop Down" in NAV 2013 Pages is completely an "intrinsic" function in the NAV "executable" itself, or whether it calls any Objects in NAV (and if so, which one(s))?

I tried placing Breakpoints in a few "suspect" codeunits and then did a "Send as Email Attachment". It produced an email with the HTML attachment just fine, but (apparently) without hitting even the Mail codeunit at all!

BTW, my question is for any and all of the Print & Send functions, not just the Send as Email Attachment" one.

Thanks In Advance!
