ESC Doesn't work

[soheil-zz]

<KeyHandler keyEventName={KEYPRESS} keyCode={27} onKeyHandle={() => this.dismissOverlay()} />

That's what I have and it doesn't work. If I put 13 it'll work fine with Enter.

In this case your keyEventName needs to be KEYDOWN or KEYUP not KEYPRESS.

PS I recommend not using key codes but key values like this:

<KeyHandler keyValue="Escape" onKeyHandle={() => this.dismissOverlay()} />

Note to self: it's important to write documentation for this behaviour https://github.com/ayrton/react-key-handler#key-event-names
