Word 2013 showing two pages side by side

I'm not a big fan of Word, as I don't find it very user-friendly; never-the-less I use it a lot.

If you select the all the content of a page (by clicking & dragging the mouse, for example), then select Delete, the page is deleted. If it is a blank page, I click at the bottom of the previous page (usually the end of the last word), and then click at the beginning of the blank page. That selection spans the "page break." Then selecting Delete will remove the blank page.

Yes, there is: How to Create a Master Document in Word 2013

Start a new, blank document in Word and save the document.

Click the Outline button on the View tab. On the Outlining tab in the Master Document group, click the Show Document button.

More choices appear in the Master Document group. One of those choices is the Insert button, used to build the master document. Click the Insert button.

You will see the Insert Subdocument dialog box. Use the Insert Subdocument dialog box to hunt down the first document to insert into the master document.

The documents must be inserted in order. Click the Open button to stick the document into the master document.

If you’re asked a question about conflicting styles, click the Yes to All button. It keeps all subdocument styles consistent with the master document. 8Save the master document when you’re done.

At this point, the master document is created. You can edit the headers and footers, create a table of contents, and work on other items that affect the entire document.
