Opponents moving almost instantly

 I've been losing games where I have a big time and material advantage, and the opponent makes moves so fast their remaining time doesn't materially decline.   When looking at the move replay, the moves on the other side are happening so fast only .1 second was being removed from their timer.  An opponent made nearly ten moves in 1 second.  Am I missing a feature where I can queue up the next move without moving my mouse and clicking it?  It's like the opponent switches on some turbo mode at the very end so I lose on time no matter what. I've seen it twice now in the past week.  

Thanks, I appreciate that info.

Hi , there is a catch here....if you pre-move , to be pre-move you got to be 0.1sec click move mouse -otherwise it wont be "pre-move" , as your opponent is 0.1sec on every of his moves.
