Hi,
I also spent a couple of hours trying to find such shortcut without success...
Honestly,
THIS IS A MUST HAVE FUNCTIONALITY in my opinion for us programmers in UE that
HATE to continuously have to switch back and forth between keyboard and mouse.
How happy was I when I found the addition of this integrated Console SSH/Telnet window that has auto hiding function. It's very cool to use for code testing on remote servers/hosts.
BUT, I got a quite disappointed when could not find a way to toggle between my Code window and the SSH/Telnet Console.
To be honest, I'm almost hoping that there is a way/trick to do that hidden somewhere in the application so that this post would be irrelevant

Don't get me wrong here : Being a long term user of UE, I'm very happy of where this great software has evolved to and it provides me all the functionalities I require in a great single product. I'm using it both personally and at work where this application covers about 75% of my every day tasks.
