I just downloaded the Kindle Modern UI app for Windows 8, from the Windows Store. I'm using Windows 8 on a regular PC with mouse, i.e. no touchscreen or touchpad capability.
When I launched the Kindle app and logged in to my Amazon account, I could see a list of the Kindle books I had previously purchased, in the "Cloud" view. I clicked on one of the books, it downloaded, and I got into the full-screen reading mode. If I move my mouse pointer to be in the left side of the screen, I can see a "left" icon appear to change the page; and similarly for the right side of the screen. I can select text to create highlights, etc.
However, I can't figure out how to return to the main screen / library view that I initially saw when I launched the app. How to return to that screen? It isn't obvious or discoverable! I've tried moving my mouse around and clicking in random places on the screen, to no avail – though I did discover the text highlighting capability.
So, to get back to the library view, where should I place my mouse pointer, and where should I click? Is there a gesture I need to do? Do I need to use the keyboard? Is there a manual or online help for the Kindle app for Windows 8? Feeling like a fish out of water with this modern UI app ;-) Thanks.
