oddball (XT PC-era?) keyboard - "dejag" etc controls

Rescued a keyboard from the dump earlier which is about the same style/size as an IBM model F, only a darker grey color (and not a buckling spring mech). Layout-wise, there are no F-keys at all, but keys on the numeric keypad are labeled things such as 'pan', 'curs', 'local', 'dejag', 'vern', and then there are eight status LEDs above the keyboard area (on-line, local, interp, busy, pan, cursor, dejag, 2nd). Does this critter sound familiar to anyone? I didn't see anything at the dump that it obviously belonged with, but I may return tomorrow and double-check, and knowing what I was looking for might be helpful. Of course it's possible that whatever it hooked up to is long-gone, or even had already been hauled off from the drop-off area for processing. cheers Jules
