I am currently trying to detect which keys are currently pressed at any given time. Like others have said, I used the keydown and keyup events and log the keyCodes to an object. I also added console.log statements in my keydown and keyup listeners. Currently, everything works well except when three keys are pressed simultaneously in a triangular shape (on a QWERTY keyboard: ["T", "G", "Y"], ["4", "5", "R"], etc.), the keys don't log as expected: either one or two logs, or none of them logs. I wonder if there's a way to get around whatever limitation is causing this?
