Town took the lead through Rory Fallon but Freddy Eastwood equalised and Keane's side could not find a winner despite playing against 10 men for the final half an hour following Marlon King's red card.
Keane said: "We had good possession, good movement, I definitely feel it is two points dropped.
"We could have been cleverer when we were up against 10 men."
