A:AnswerYes this keyboard functions as a protective case for the Google Pixel Slate. It uses very strong magnets to attach itself to the tablet. It folds up to use as stand and when in the tablet orientation, it protects the back of the tablet. When not in use it folds over and protects the tablet front and back. This keyboard is very versatile and very useful!
A:AnswerAs of now no. There is only the American english keyboard layout. However There are settings in the slate and input method that should allow for typical multi language input. Usually after setting a second language you will be able to hold keys for more letter / language options. For now this is your only solution.
