Overlay and Attribute Select Keyboards: These keyboards are equipped with highlight, PS and color select function keys (12 PF keys on right-hand side of the keyboard). They provide operator selection under program control, of highlight, PS and color attributes. Except for the color marking and annotation on the 12 PF keys on the right-hand side of the keyboard, the Overlay and Attribute Select keyboards appear identical to the equivalent non-Overlay and non-Attribute Select keyboards. Use of keys to select a feature not on the display will cause an error indication in the operator guidance row on the display. The uppercase and alternate shift of these 12 PF keys are used for attribute selection and are, therefore, not available for normal program function use. Limitations: Attribute selection is NOT supported for keyboards on a 3279 Model 2B or 3B attached to a 3276, OR for keyboards attached to a 3279 Model 2A or 3A.
