Indeed.

First of all, that *is* possible, but it would be hard.

Second, I was thinking of adding support for selecting a range of lines by
dragging on the sidebar, similar to the new editor window behavior with
line numbers (try it!). It *would* be possible to make this also highlight
the sidebar prompts as selected, and include them when copying. This is
very similar to the above, actually.

Even simpler would be adding a "copy as doctest" context-menu (right-click)
option, which wouldn't require users to discover selection using the
sidebar. IMO this is more obvious and easy to discover, and so better
suited for IDLE.
