Here: http://mbork.pl/2022-09-17_Safe_killing_with_Emacs Note: as mentioned in the mode docstring and in the blog post itself, this is not really "safe" - you can still lose text in various ways when using this code. However, if you stick to the the basic kill/yank cycle (so, no M-y, no undoing the yank...), you should be good. I am convinced that making this code /really/ "safe" (read: make it impossible to lose text) is impossible. After all, sometimes deleting is what you actually /want/. ;-) Also, it seems not to like `append-next-kill'. Still, as a PoC it seems to work pretty nice. Best, -- Marcin Borkowski http://mbork.pl
