Keen camper sleeping here (6)

I believe the answer is:
intent
'keen' is the definition.
(I've seen this before)
'camper sleeping here' is the wordplay.
'camper sleeping' becomes 'int' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'here' becomes 'ent' (I've seen this in other clues).
'int'+'ent'='INTENT'
Can you help me to learn more?
(Other definitions for intent that I've seen before include "Firm - plan - steadfast - purpose" , "Resolved; purpose" , "'Purpose, aim (6)'" , "Focused" , "Bent on, resolved" .)
