Present spot useful for controlling channels (3,6)

I believe the answer is:

the remote

'useful for controlling channels' is the definition.
(remote control for a TV)

'present spot' is the wordplay.
'present' becomes 'there' (I've seen this in other clues).
'spot' becomes 'mote' (I've seen this before).
'there'+'mote'='THE REMOTE'

I've seen this clue in The Guardian.
