where can i find this "box lesson"...and how to a convert the music from ye yaile chere to the key of my accordion?

Box Lesson is Big Nick's website. www.bignick.net/BOXLESSONS/
The right hand keyboard is decoded for a C accordion under Lacassine tab, scale decoded. To write the tab correctly from sheet music the music must be in the key of C (for this example.) Ye Yaille Chere is a book and the version in the book is in the key of D. First transpose it and then decode it to tabs. Very laborious but if that's what works for you just do it.

Big Nick's box lessons are terrific! Shows many great tunes at full speed and slowed down. Tabs and sheet music deluxe. Has been a great help to me.

Enjoy.
