+When dividers and vertical scroll bars are both disabled for a
+specific graphical frame, Emacs separates windows on that frame with
+the help of a one-pixel wide "vertical border", see (@pxref{Scroll
+Bars,,, emacs, The Emacs Manual}).  When dividers are disabled but
+vertical scroll bars are enabled on that frame, Emacs draws these
+borders on mode lines only since the scroll bars are already
+considered sufficent for separating the windows visually.  In either
+case, borders can be dragged with the mouse in order to resize the
+adjacent windows.
