  "Toggle display of tab line in the windows displaying the current buffer.

When this mode is enabled, each window displays a tab line on its
top screen line.  The tab line is a row of tabs -- buttons which
you can click to have the window display the buffer whose name is
shown on the button.  Clicking on the \"x\" icon of the button
removes the button (but does not kill the corresponding buffer).
In addition, the tab line shows a \"+\" button which adds a new
button, so you could have one more buffer shown on the tab line."
