The elder scroll 5 arrow key is invalid.

You must press the space bar while holding down shift. If you press these two keys at the same time in the game, you will enter the photographic perspective. If you press the two keys at the same time again, you can solve this problem. If it still doesn't work, it may be that your keyboard is broken or press ESC to see if the key position settings in the option settings are correct. Generally speaking, this can completely solve this problem.
