Robbie celebrated signing a new contract on Friday with what must rank as one of his best goals for the club to put us 1-0 up after eight minutes.
Receiving a quick throw-in from Mido, Robbie flicked the ball over Robbie Savage before turning inside Andy Todd and firing past Brad Friedel.
Keano was there again to tap home after Friedel parried Mido's free-kick after 42 minutes and all looked rosy.
However, Florent Sinama Pongolle replied a minute later and Rovers took a grip on the game at the start of the second half, equalising through Bellamy after 67 minutes.
To the lads' credit, they hit back straight away as Aaron Lennon carved out the opening for Mido's winner.
Head Coach Martin reflected: "Robbie Keane made the difference because the first goal is exactly what you have in mind with him but you can only dream about that sort of goal.
"He's done everything at the age of 25 but he still wants to be here and that's something we have to relish.
"Mido was intelligent with the throw-in as well. We usually take too long and we've said to look to take them quicker sometimes and that's what he did."
Martin was impressed with Blackburn and didn't disagree with pundits suggesting Mark Hughes' men deserved something out of the game.
"The first half was ideal with two goals but then to concede and make it 2-1 just before half-time was unfortunate," added Martin.
"In the second half they took the game to us and I thought they were terrific, and in the end I thought we were a bit fortunate. I can imagine Mark Hughes is feeling unhappy but we've had similar games this season and sometimes it happens.
"It was an essential victory for us and we know every game is now going to be a big fight."
Martin Jol described Robbie Keane's stunning opener as 'a goal you can only dream of' after Sunday's 3-2 win against Blackburn.
