No, but your environment certainly did! If it was anything like
the similar ones I spent time in, the editor was very tightly
constrained: an IBM 029 keypunch :-)
On which -- unlike insert- and delete-line operations, which were
trivial -- insert- and delete-character weren't officially
supported, but were kludgeable nonetheless: while duplicating the
bad card, you would frustrate the keypunch's attempt to advance
one of the cards -- the original or the duplicate, respectively
-- by physically holding it in place while typing the correction.
