  • Click and hold the green button in the upper left corner of an app that shows two triangles pointing in opposite directions. Do not release the button.
    • If the green dot reveals a + sign, that app does not support slit screen view.
  • While holding down on the button, drag the window to the half of the screen you want to place it in. That half of the screen will be tinted blue.
