-@deffn Command toggle-read-only &optional arg
-This command toggles whether the current buffer is read-only. It is
-intended for interactive use; do not use it in programs (it may have
-side-effects, such as enabling View mode, and does not affect
-read-only text properties). To change the read-only state of a buffer in
-a program, explicitly set @code{buffer-read-only} to the proper value.
-To temporarily ignore a read-only state, bind @code{inhibit-read-only}.
-
-If @var{arg} is non-@code{nil}, it should be a raw prefix argument.
-@code{toggle-read-only} sets @code{buffer-read-only} to @code{t} if
-the numeric value of that prefix argument is positive and to
-@code{nil} otherwise. @xref{Prefix Command Arguments}.
+@deffn Command read-only-mode &optional arg
+This is the mode command for Read Only minor mode, a buffer-local
+minor mode. When the mode is enabled, @code{buffer-read-only} is
+non-@code{nil} in the buffer; when disabled, @code{buffer-read-only}
+is @code{nil} in the buffer. The calling convention is the same as
+for other minor mode commands (@pxref{Minor Mode Conventions}).
+
+This minor mode mainly serves as a wrapper for
+@code{buffer-read-only}; unlike most minor modes, there is no separate
+@code{read-only-mode} variable. Even when Read Only mode is disabled,
+characters with non-@code{nil} @code{read-only} text properties remain
+read-only. To temporarily ignore all read-only states, bind
+@code{inhibit-read-only}, as described above.
+
+When enabling Read Only mode, this mode command also enables View mode
+if the option @code{view-read-only} is non-@code{nil}. @xref{Misc
+Buffer,,Miscellaneous Buffer Operations, emacs, The GNU Emacs Manual}.
+When disabling Read Only mode, it disables View mode if View mode was
+enabled.
