Working with dual monitors

[Janine]

I have one presentation going on one monitor and I am working on the next
one. How do I send it over without interupting the presentation already in
progress?

You want to create a link at the end of the first presentation so the next
click opens the show you are working on. The key is not changing the file
name and once the show is live (eg. link used to open), it is no longer
editable.
Here are two tutorials on linking presentations:
