Navigating doc typos

Some "downloading" that should be "uploading".
Some bullet points with "code" items were rendering with bold, italics on the published page. These seemed to be bullet points that had 3 spaces at the start of their 2nd line of text. Other bullet points that rendered correctly had only 2 spaces. So I removed the extra space. I hope it renders nicely in the published form - it is a bit hard to know in the GitHub Preview, because that is trying to show change-sidebars and differences also.
