mouse ahead

mouse ahead vi.  Point-and-click analog of `type ahead'.
   To manipulate a computer's pointing device (almost always a mouse
   in this usage, but not necessarily) and its selection or command
   buttons before a computer program is ready to accept such input, in
   anticipation of the program accepting the input.  Handling this
   properly is rare, but it can help make a {WIMP environment} much
   more usable, assuming the users are familiar with the behavior of
   the user interface.
