Left Key? Right Key? Does This Refer to the Arrow Keys?
Most of the commands in edit mode refer to a combination of Left and another key or Right and another key. I do not have keys called left or right so I assumed that this referred to the arrow keys but that doesn't seem to work.

In the handbook Left, Right, Up, or Down refer to the arrow keys as you correctly guessed. Can you give an example of when the key combinations are not working for you? Did you double-click to begin edit mode first?
