lineKey.reassignment.enabled lineKey.X.category="EFK"

Good afternoon,

Anyone one have any information on how to use

lineKey.X.category="EFK" 

For example if  you were to be utilising the line function it would be

lineKey.1.category="line"lineKey.1.index="1"

Line and an index of what line.

If you were to be using the BLF

lineKey.1.category="blf"

It uses the order of

attendant.resourceList.1.address="500"attendant.resourceList.1.label="Jaymee"attendant.resourceList.1.type="normal"

How do I set "what EFK" the button will be triggering?

lineKey.X.category="EFK" 

(Obviously lineKey.reassignment.enabled = 1)

Thank you
