How to activate Photon Blast??

[psu000]

Can't seen to find the button from keyboard or joypad to activate the blast. My mag (Lv30) is charged up just don't know how to activate it.

Can someone please give me an idea how to start the photon blast. Thanks

Go to your customization, first icon second option, it should be under one of the tabs as an active skill, set it somewhere 1-10 use it!
