Thank you for your explanations!
No problem!
Oh I see... Then what about this: maybe simply add links somewhere on top of the page to these two ladders? Maybe one at the left of "M" (the "M" from "MATR") and one at the righ of the "R"? Or at any other place you may find suitable? Would that work better?
Have you seen the "?" on the column headers? Clicking the "?" once will keep it open, so that can access the links involved in a particular formula. Is this something like what you are looking for?
