Note

If the keyboard shortcut Ctrl + Alt + arrow key does not activate the ACRON Move function, but rotates the screen view instead for example, the shortcut is being used by a graphics card driver. Press Ctrl + Alt + F12 to open a menu in which you can change the graphics card shortcut assignment.
