'Javascript detection of browser focus/visibility when mac screenshot tool is used
I'm building a game and I use the keypress events to detect certain keys being used. Basically updating a boolean flag via addEventListener for keydown and keyup. Works great.
However, I use the "shift" key for a certain powerup in the game. And when users try and take screen recordings via Mac screenshot tool (CTRL+SHIFT+4 or CTRL+SHIFT+5) the shift key causes the power up to get triggered.
It's a mild annoyance, but I've been trying to detect it when this happens via
tracking document.visibilityState and document.hasFocus(). But neither of them change when the user presses this keyboard combination of Mac.
Is there a way to detect this via Javascript so I can clear the keyup event for the Shift input when it happens?
