Operating Procedures
Partitioning
The Partitioning function is a controlled function. To use the Partitioning function, your
display station must be attached to a controller that supports partitioning. The display
receives partitioning commands from the host only while in Native mode.
To scroll vertically through data in the viewport during partitioning, the Back and Fwd
(Forward) keys are used in the following manner:
To scroll forward vertically (down through the data in the presentation space), press and
hold the Alt and Fwd keys. This moves the data up the viewport.
To scroll backward vertically (up to the beginning of the data in the presentation space),
press and hold the Alt and Back keys. This action pushes the data down the viewport.
Extended Select Function
To perform the Entry Assist and Response Time Monitor functions, press the Extended
Select (ExSel) key while the display station is in Native mode. The display station must
be attached to a properly configured Memorex Telex 1274 Control Unit at firmware
release 11.0 or higher, a MTX/MTC 1174 Network Controller, or any other properly
configured controller that supports Extended Select.
