 This variable's value is the output speed of the terminal, as far as
 Emacs knows.  Setting this variable does not change the speed of actual
 data transmission, but the value is used for calculations such as
-padding.  It also affects decisions about whether to scroll part of the

-this way despite the fact that a window system has no true ``output
