Well, the keyword here is DOS, if each and every one of the programs that 
were to be used with this utility would use DOS in text mode for doing screen output,
this would not be hard to do. But they don't and won't. That's why there is no
way to trace screen output, like for example on a VT100 terminal.

So don't waste your time, it it was possible the PC would have such a key on the
keyboard, (as terminals often have)
