Need Help on Advanced Tutorial PC

Select ability and select grenade throw at the beginning of Advanced Tutorial for PC

It gives a unrecognizable command? Looks like a mouse, and then click but I cant tell? is there a way to hotkey something different

or does anyone know what it is? I can’t get past the very first part of the advance tutorial… seems like an issue with the initial design

has a picture of a mouse I believe, with all four direction arrows
