Oh that is interesting - I only worked directly with a few terminal systems and never twigged that the 3270s were doing anything fundamentally more sophisticated than WYSE or DEC vt200s. I do remember tabbing between fields on an IBM3090 library catalog search form, though and it being basically an edit and submit process.
