Do you mean on computers, or are you talking about typewriters? I'm a little unclear on what you're asking, but I have a feeling that you might be mistaken about the timeline of some of the relevant events.

If you can clarify your question I can most definitely provide you with an answer.

Meanwhile, you might be interested in these answers I gave about a month ago on some related topic. It's a little disjointed but parts of what I wrote there may relate to what you have in mind.
