Re: [Texmacs-dev] Overwriting selections

[Joris van der Hoeven]

Dear Norbert,

Thanks for reminding this issue to me; I put it on my TODO list.
It may require some non trivial modifications, because we should
be able to restore the state of the pointer and selections after 'undo',
as pointed out in the subsequent posts to this message.
This would actually be good anyway and useful for many other things.
Also, insert_tree seems a bit dangerous as a place to do the cut,
so I will need to refactor some code.

Best wishes, --Joris
