In the middle of a long catalog of conversion woes, Annie observes:

I don't know if it's the actual source for Xy's usage, but all
Borland programs (including their Pascal and C++ editors) use

   Ctrl-Ins  copy to clipboard
   Shift-Del  cut to clipboard
   Shift-Ins  paste from clipboard
   Ctrl-Del  clear clipboard

and one often sees these conventions followed in other companies' products.

Many of the key mappings in Borland products are holdovers from
WordStar, which most of their early customers knew. However,
pre-Turbo Pascal WordStar certainly didn't do clipboards, so I
can't explain the origin of this particular set of key combinations.

Dumb clipboard operations have no stack; only the latest contents
can be pasted, and any subsequent cut or copy will overwrite
previous contents. This sound like exactly what you were looking for.
