Enter is defined as x’F1′ – look for that and disallow any processing. This would let you keep other function keys on the screen active. You can even check for Auto-Enter, x’3F’

I like the attention indicator byte – I haven’t bothered attaching an indicator to a function key in ages. I just compare the field defined on the INFDS to pre-defined constants. You can find the definitions of the returned values here.
