Split pages at cursor - create new page

A great but simple time-saving feature that a program like Scrivener has been the ability to create a new sub-page at the cursor by keyboard shortcut or command. It creates a split at that point with the rest of the content going to the next page.

When you are writing, or when you import a large document, it makes it much easier to split it up into subsections rather than cut/copy, create a new page, and then paste.
