Confusion with Laptop controls w/ one scene. S2E1.

So I just downloaded S2 on my Acer Chromebook 2015 laptop and then I am currently stuck on the 1st episode fighting this one grunt with a gun and then a prompt comes up that has two white dots and a gamepad symbol in the middle(dunno how to show screenshot). It looks like I need a controller but don't currently own one. I have tired pressing the 'q' and 'e' as well as 'a' and 'd' and moving my mouse around but nothing works.

Should I order a controller or is there something wrong I'm doing?

Thanks.
