Key combinations on Chrome OS alternate app/browser windows between two positions. On a Chromebook, the alt key combined with either the left or right bracket key lets you quickly reposition a window on the screen (Figure A). Specifically, the key combination:
- alt + [ moves a window to the left (and, if pressed again, around the center of the screen), while
- alt + ] moves a window to the right (and if pressed again, around the center of the screen).

On a Chromebook, press alt and [ to dock the active window to the left of the screen. Press the combination again to return it to the middle of the screen. (The combination of alt and ] does the same to the right.)
