Shuttle control is no longer part of Premiere.
Search for the very long recent thread on this subject if you have to. (Its controversial to a few diehards and no issue to most)
JKL control has replaced it due to most users preferring Keyboard control.
JKL control has replaced it
Well...to be accurate, JKL has always been there as an option. It's not that a new way of shuttling has been added, which the word "replaced" implies. It's just that the other option has been removed.
I missed it too, but I've learned to use the J-K-L and frankly, I kind of like using the keyboard. I'm learning to use more keyboard shortcuts and my speed has improved quite a bit.
...this just in from the Department of Dinosaurs: Thank you all for the advice; I have learned the J-K-L shortcut and understand the reasons for the change. It is actually much easier than using the shuttle.
Again, thank you all for the advice.
