Thanks!

Bonus follow up question: Is there a way to keep the in-game chat open a little longer, or just open? It closes so fast.

I have found simply cancelling my queue and starting a new one to very often throw me into a match within seconds.

How do I chat?

I see no key assignment for chat. Also, I cannot manage to type anything in the post-game windows, even if I can select it.

I see a "short commands" key, but I believe that's for automated call-outs?
