Hello!A hot hearted man.:)

The left and right keys of the mouse.
What is the corresponding key code？

And then the Z axis.The Z axis is the mouse's pulley？
No, so what's that？

Do you tell me？thanks.:D

@Edgar Reynaldo
hello！
Thanks you.
What I need is not this.

What I need is:
Like the keyboard: "allegro_key_up"

The same, the left mouse, the right mouse button.
What are they？

@Edgar Reynaldo
Thanks.
I know, this is the mouse was pressed.It's “event.type”.

But what I need is “event.mouse.button”.
It's like it“event.keyboard.keycode”

@Edgar Reynaldo
Hmmm.That's what I didn't notice.

Thank you, hot people.:)
