The [+/-] key generates the following mathematical character sequence:
+, -, *, /, =, (,),
The [.] key generates the following punctuation character sequence:
.,?, :, ;, ,,’ ,”, $,
Once the desired alpha-numeric character is obtained, use the left or right arrow to select a new position.
Alternately, pressing different key moves to the next position.
Text Table Object
When editing a Text Table Object, all the keys except the Up and Down arrow keys are grayed and
disabled. The next text selection is made by pressing either the Up or Down arrow.
Time/Date Object
When editing a Time/Date Table Object, all the keys except the Up, Down, Left and Right arrow keys are
grayed and disabled. The specific field (i.e. hour or minutes) is selected using the Left and Right arrows.
The value in the selected field is changed by pressing either the Up or Down arrow.

Screen Navigation
To allow the operator to change screens, a screen jump object is generally used. This object may be
visually represented as a 3-D button (responding to touch) or remain invisible and logically tied to an
OCS register. An optional system ICON may be configured for display along with the legend, which aids
in identifying the object as one that causes a screen change (shown below in figure 10.3)
Figure 11.3: Screen Jump Object (configured for a specific screen)
The QX351 had the ability to store up to 8 screen jumps and then transverse back through those screens
when the desired operation is complete (useful for virtual menus). On OCS models that contain a front
panel ESC key, each press of the ESC key transverses back one screen; however, since the QX351
does NOT have an ESC key on the front panel an alternate method is used. Screen jump objects on a
QX351 may be configured to simulate an ESC key. Typically, screen jump objects simulating an ESC key
are labeled Back or Previous to indicate to the operator that it is possible to transverse back to a previous
screen.
