Apply space or transitions to multiple clips

If I have clips placed back to back from each other on the timeline, can I select all clips then add space in between them(empty space so a black screen with no audio). Or maybe add transitions to all of them at once?

Hey Grant

Not at once... You could have the space ready in Source and quickly Insert Edit it in between every cut.
You could also select all cuts on one side only with Selection tool and Cmnd/Ctrl pressed, then with the "," key remove a few frames from all starts/ends of your cuts... at once.. sort of.

Or maybe add transitions to all of them at once?

Select all cuts using Trim tool (T) and dragging around them.
Hit Cmnd/Ctrl + T to add transition to all.
