Keyboard in tablet mode. I was looking for something similar but almost nonexistent. As mentioned by a previous reviewer, the tablet does not lock when both covers (on the back of the screen and on the bottom) are used. In tablet form, the part that attaches to the back of the display can be used to cover a Chromebook's touchscreen. It is easy to use and projects with a touch screen. I ordered a 12.2 inch screen to fit my Samsung Chromebook.
