 Defined at [web/src/engine/keyboard/src/keyEvent.ts](https://github.com/keymanapp/keyman/blob/master/web/src/engine/keyboard/src/keyEvent.ts), the `KeyEvent` is used to represent incoming _and_ potential keystrokes.  This type is what the JS-keyboard processor references when evaluating keyboard rules during its keystroke processing.  For versions of the engine that support AltGr aliasing, such aliasing will be applied during generation of `KeyEvent` objects.
 
-Note that for predictive-text's fat-finger correction functionality, the engine will also generate versions of this type for _unpressed_ keys _weren't_ into the keystroke processing engine as well.  Each will be applied to a `Mock`-cloned copy of the active context-state.
+Note that for predictive-text's fat-finger correction functionality, the engine will also generate versions of this type for nearby but _unpressed_ keys into the keystroke processing engine as well in order to facilitate predictions that follow context manipulations that could have resulted from specialized rules or reorders on neighboring keys.  `Mock`-cloned copies of the active context-state will be leveraged to prevent unwanted manipulation of the true context source.
 
 ### `isSynthetic`
 `isSynthetic` should be set to `true` if generated through interaction with an on-screen-keyboard or for fat-finger simulation.  It should only be set to `false` if sending the basic key-event data through to the destination, without rule processing, leads to default handling picking up the slack.  Browsers provide default handling of keystrokes not directly defined within keyboards, but this is not available for keystrokes against the engine's OSK without internal support.
