@cindex read-only buffer
A buffer can be @dfn{read-only}, which means that commands to change
its contents are not allowed. The mode line indicates read-only
-buffers with @samp{%%} or @samp{%*} near the left margin. Read-only
-buffers are usually made by subsystems such as Dired and Rmail that
-have special commands to operate on the text; also by visiting a file
-whose access control says you cannot write it.
