New saved window shortcut

Unless I'm missing it, I can't see a way to create a new saved window shortcut.

The only way i can see to do it with the + button on the left sidebar.

I use saved windows as 'tasks/projects' and so i just want a quick way to create a new task/project and get working.

zee What would the shortcut be?

When i used Arc i set it to cmd-alt-n but honestly whatever it isn't being used should be fine. Thanks

zee What would happen after pressing this?
