To prevent confusion, facilitate search, etc., would a moderator please replace (add synonym, then merge appropriately) the tag
killing with the better name
"Killing" in Emacs can also refer to killing a buffer or killing a process, and it might even be (incorrectly) used for deleting a window, frame, etc.
For instance, this question, about killing processes, used tag
killing (I removed it):
Elpy: how to stop the underlying "py.exe" process?
The tag needed is
killing-text, for killing text. If there is ever a need for other "killing" tags they can be added later.
