Which button do I “HOLD” in Mission 33

far-cry-3pc

When I get to the torture scene, I'm prompted to hit left mouse twice to throw two punches at the prisoner. When it's time to jam my thumb into his wound, all is see is HOLD but no button prompt. I don't have any keys unbound and nothing seems to work. So now I'm stuck at this point. What am I supposed to press?

By default, it should be the spacebar.
