- You can use kill commands in read-only buffers. They don't actually
-change the buffer, and they beep to warn you of that, but they do copy
-the text you tried to kill into the kill ring, so you can yank it into
-other buffers. Most of the kill commands move point across the text
-they copy in this way, so that successive kill commands build up a
-single kill ring entry as usual.

+@subsection Killing on Graphical Terminals
+
+ On multi-window terminals, the most recent kill done in Emacs is
+also the primary selection, if it is more recent than any selection
+you made in another program. This means that the paste commands of
+other applications with separate windows copy the text that you killed
+in Emacs. In addition, Emacs yank commands treat other applications'
+selections as part of the kill ring, so you can yank them into Emacs.

+@findex delete-selection-mode
+ Many window systems follow the convention that insertion while text
+is selected deletes the selected text. You can make Emacs behave this
+way by enabling Delete Selection mode, with @kbd{M-x
+delete-selection-mode}, or using Custom. Another effect of this mode
+is that @key{DEL}, @kbd{C-d} and some other keys, when a selection
+exists, will kill the whole selection. It also enables Transient Mark
+mode (@pxref{Transient Mark}).
