Doubt for Orbwalker

When I'm playing a game with a champion (sniper) who has a lot of attack speed, when I'm with the orbwalker(Space) is pressed it does not shoot in the same way as if I hit stopped without the orbwalker is there any configuration for it to shoot faster?

The orbwalker has a few options, one of which is pushing, the heading is different but the config menu is the same, though it needs to be set to a different hotkey.
