In Helldivers 2, you can use macros using the Keyran driver to quickly activate stratogems. The setup is simple - just set the macro activation button and use the standard W-A-S-D keys to control. In battle, after pressing Ctrl, press the macro activation button to instantly trigger the stratogem. This method will allow you to do this quickly and efficiently, without having to change the game settings. Even when recording a video or broadcasting, it will look like an instant activation of the stratogem.
