Autohotkey trying to use mouse movement to send keystrokes_redact

I am trying to write a simple script that will combine the holding the XButton1 on the mouse and moving the mouse left or right to simulate holding down the XButton1 (on the mouse) and pressing either A or D to freelean. It is a shooter game. So instead of using the mouse in combination with the keys, I just want to hold down the XButton1(side mouse button) and slide it left or right to simulate using the keyboard keys. I know it is possible but I can't seem to get anything to work. I am using Autohotkey v 1.3 I think. I am not using 2.0 bc of issues with new syntax. Any help will be appreciat
