(probably more than I know) IBM wasn't consistent with PgUp/PgDn, either. The 122-key PC/3270 keyboard has the magic 6 (which are above not an inverted T, but a cross, with Home in the center) as PA1, PA2/PgUp, and Jump/PgDn (with PA3 on the Alt) across the top, then backtab/End, Insert, and Delete.
