Shift+3 gives the Timeline panel focus.
Shift+4 gives the Program Monitor focus.
You can customize these shortcuts any way you want.
Hi Jeff. Thanks for the reply.
I already use Shift +3 but I was really looking to toggle between the two - such as Ctrl + Tab (which doesn't seem to work!)
Ctrl+Tab only works with MDI windows, which Adobe dumped after version
2.0. The shortcuts I gave you is how you have to work in the Drover
workspace, which is used in CS3 and CS4.
Did you want a toggle only between the PM and the Timeline panel?
Should the toggle cycle through all of the panels? What do you need to
do that Shift4 and Shift3 can't do? The answer to these questions
should be part of a Feature Request if they're important to you.
