Just know about this feature in the "Middleware Parameters" video and I think it doesn't work very well here.
Specs: OS X El Capitan public beta 2. Safari 9.0.
Open Laracasts.com. Hit "s", it will open the search bar at the top.
Hit "Esc" to hide the search bar. If I'm not clicking anywhere on the page, hitting "s" again won't work.
As soon as I click the page, the "s" works again, and the search bar already has an "s" in it.
Is is a known bug, intended behavior, or I'm just on an unsupported browser/OS?
