the dome glitch is not a strafe it is just a fast crouch jump. make a macro that presses a then crouch about 0.3 seconds after a. this will jump then press crouch. then assign that to a tac and try the glitch with this tac, you will be able to do it so easy by using this to jump instead of normal jumping
To sum up, make a crouch jump macro, then use it to jump to the window
