About the Recognition System
9-15
This section describes only those user preferences for which the system provides a
NewtonScript interface. It does not provide a comprehensive summary of the user
interface to recognition, which may vary on different Newton devices. For a
description of the user interface to a particular Newton device, see the user manual
for that device.

The user preference settings for recognition that this section describes are stored as
the values of slots in a system-maintained frame that holds user configuration data.
These slots are described in "System-Wide Settings" (page 8-2) in Newton

Programmer's Reference.
The user preference settings described here may be affected by the setting of a
protoRecToggle
view associated with the view performing recognition. For a
description of this view, see "RecToggle Views" beginning on page 9-18.
Recognition-oriented user preference settings may also be overridden by a
recConfig
frame associated with the view performing recognition. For complete
information on
recConfig
frames, see Chapter 10, "Recognition: Advanced
Topics."
Handwriting Recognition Preferences
