What are PD1 and PD2 Keys on 4704 Boards stand for?

[MrDuul]

Wondering if anyone out there knows what the PD1, PD2 keys are for on 4704 keyboards? Also Erase POF key, maybe there is a wiki for this?

I don't know where else to post this.

I was wondering this as well. My F107 has PD 1, PD 2, and PD 3 keys.

Afraid I can't help on the PD keys but could "Erase POF" actually be "Erase EOF" = Erase to End of Field?

Paragraph Delete maybe? Or Page Delete?

Paragraph Delete maybe? Or Page Delete?

Good theory, but that doesnt explain why there are 3 of them. We need someone who actually used a 4700 banking terminal back in the day to weigh in on this discussion.

I have bought 122-key Model F terminals with complete sets of PD-1 through PD-24 function keys.

Well this should be the greatest mystery of all keyboard questions now.

Chyros paragraph delete sounds epic.

The P at least seems to stand for Program or Programmable.

According to IBM, the PA keys stood for Program Action keys: https://www.ibm.com/support/knowledgece ... fkeybd.htm

I've got an M122 with an ErEOF (front print Recrd) key and another German M122 with a Lösch Feld (front print Aufz) key in the same position. So Erase to End of Field makes a lot of sense.
