A main feature of the interface is Leaping, a means of moving on-screen via incremental text-search. The system provides two commands, Leap-forward and Leap-backward, invoked through dedicated keys, that move the cursor to the next and prior position that contains the search string. Leaping is performed as a quasimode operation: press the Leap key and, while holding it, type the text that you want to search; finally release the Leap key. This process is intended to habituate the user and turn cursor positioning into a reflex.
