Using Avid Media Composer 5.5 on a new 13" Macbook Pro. Using a regular keyboard you can move the timeline position indicator precisely just by typing the sign + or - and the number of keyframes. Now... how can I do this on a MacBook Pro keyboard? I guess it's some kind of keyboard shortcut I am missing, I just can´t find anywhere. I would appreciate any tip on this. It's a simple feature I need to use all the time!
