You can display the PFK numbers on 3277-2 consoles and then point
to them with the selector pen. Pointing to a number has the same
effect as pressing that key. To display the PFK numbers, use the
CONTROL D,PFK command. To erase the numbers in the PFK line, use
the CONTROL E,PFK command.
Example:
To request a display in the PFK display line (this line is located
immediately above the instruction line), enter:
CONTROL D,PFK
In response to this command, a display similar to the following
appears in the PFK display line:
1 2 3 4 5 6 7 8 9 10 11 12
Only those numbers that have been designated for PFK command entry
appear in the display. Once you have requested this display, you can
leave it on the screen; the PFK display line is not used for any other
purpose, even when the key numbers are not displayed. To erase the
display, enter:
CONTROL E,PFK
