Did you know that the timeline can hold a number of Projects, but only one Project is active and visible at any one time.
The timeline is, in fact, a stack of active and non active projects.
The non-active projects in the stack can be made active and visible by selecting the left and right arrows
If you hold on either of those arrows you’ll see all the other non-active projects in the stack
keyboard shortcut that scans through the timeline stack:
Option+[ for the left arrow and Option+] to activate the right arrow.
Select the centre downward arrow, to Duplicate, reveal in Browser, and close projects in the stack.
