Re: Copying multi-range selection

We worked on this some years ago, and found that the cut/copy/paste were
very, very complicated to get to be natural, and ended up dropping it.

The problem is that if ...ABC... are adjacent ranges on the screen in the
source (each letter is a range), people expect to see ...ABC... when it is
pasted in to replace ...EFG.... You end up having to do a "reverse bidi" to
see what combination of characters could produce the end result. Might be
possible, but would need some serious UI research...
