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.
