What is written on the side of the 'mystery key' on an IBM PC 3180 keyboard?
To be more specific, I'm talking about the text seen here...

While the key itself is effectively "Delete" (or "strikeout" as I would like to think of that symbol) the picture is not very clear and I cannot find any clearer images on the internet.
Looking at the rather fuzzy top image I believe that what may be there is effectively
but with "abc" and so denoting that it is to delete an entire word as opposed to an individual letter.
You can just about make it out if you squint a bit and use a bit of imagination...
I found a slightly better angle here and it's just looking more and more like "abc(strikeout)" to me
On the Affirmative 1227T, the corresponding key is marked 'Delete' on the top and 'DelWd' ("Delete word"?) on the front. So I'd guess that it's the same strikeout symbol, only striking out a word rather than a character.
