I'm getting key events twice when I trigger a recomposition in onPreviewKeyEvent, is this a known issue?
✅ I just needed to only respond to key down events

The handler is:

.onPreviewKeyEvent {
    when (it.key) {
        Key.Escape -> {
            editing = false
            true
        }
        Key.Enter, Key.NumPadEnter -> {
            editing = !editing
            true
        }
        Key.Plus, Key.DirectionRight -> {
            setMax(max + 1)
            true
        }
        Key.Minus, Key.DirectionLeft -> {
            setMax(max - 1)
            true
        }
        else -> false
    }
}

where setMax is a passed-in setter that will trigger recomposition.

I can work around it by using:

scope.launch {
    delay(100)
    setMax(max - 1)
}

the delay is necessary.

you can filter it by event type. e.g.:

it.type == KeyEventType.KeyDown

Yeah, that's what I ended up doing. It might be nice to have onKeyDown(key: Key, action: () -> Unit) style modifiers, eventually, I'm ending up with rather clunky handlers for onKeyEvent.
