If I highlight something and then run kill-region (C-w), it

gets killed. That's good.


But if I highlight nothing, and accidentally run kill-region, the

rest of the document starting at the cursor gets killed.


I know it sounds stupid, but more than once I have killed a lot of text

like that and not realized it until much later, thanks to Git.


Emacs is wonderful, thank you so much.

When I try this without having any region, Emacs says

  The mark is not set now, so there is no region

and doesn't kill anything.

So I'm guessing that you do have a region in those cases, just not a
highlighted one.  You can make it highlighted by "C-x C-x" (twice, if
you want to return to the original location).  I suggest to grow a
habit of doing that before each C-w, because, really, Emacs does here
what you told it to do.

Thanks.

That means there is a mark at the end of the buffer.  Set
mark-even-if-inactive to nil, and kill-region will complain instead.
