huntsman v2 macro

Hi guys Could anyone help me all I'm after is a simple macro . I play PUBG on pc with mouse keyboard and the inventory key i use is E now with PUBG you press the E key the inventory opens when you press the E key again it closes the inventory . I'd like to make a macro that changers that to hold instead of toggle so i hold the key down it opens the inventory once i release the key the inventory closes Thanks
