A.先将 A 键映射为 B，再将 B 键映射为 A，即可实现两键交换
A. First map the A button to B, and then map the B button to A, so that the two
buttons can exchange function.
(在键位映射模式下，实现方法为按 A B B A）
(In the button mapping mode, the operation is to press A, B, B, A)
B. 将 A 键映射为 B，再将 B 键映射为 X，再将 X 键映射为 A，即可实现三键交换；以此类

B. Map the A button to B, map B to A, and then map X to A, so that the three
buttons can exchange function; and so forth
(在键位映射模式下，实现方法为按 A B B X X A）
