Arrow keys move screen instead of moving from cell to cell

[LuisGe]

On the keyboard, the arrow keys when used move the screen instead of moving
to the next cell. How do I switch back to moving from cell to cell?

where is the scroll lock?

It's a key on your keyboard.

My scroll lock button is to the right of the F12 key and between the
"Print Screen/SysRq" and "Pause/Break" keys.

But my keyboard is a standard USA desktop keyboard.
