Closing Projects without Closing DR

This seems so basic yet not working.
I did not find this addressed anywhere in the DR Manual.
Say, I’m in a project and I either want to save it (as a modification of a project already created), don’t wish to save the changes or I’m just experimenting to learn how various Title Fonts, Transitions an Effects look in DR so I don’t wish to save the untitled project.
I clicked on File> New Project and I’m prompted with Save? Don’t Save? – if I choose either the current project remains on screen.
How do I open a new screen after I’ve had an untitled or Titled project open without having to close DR?
Ex. In MS Word if you wish to open a new screen to start a new document from scratch you just click Home > New Document and you can keep the document you just left as its placed on the lower taskbar while a blank document screen opens to create a new Word document.
That also allows you to click on that older document on the taskbar should you think later of a change you wish to modify that older document without closing it down.
Can you do the same with projects in DR?
Thank you!
