title: Toggle between fullscreen editor and terminal in VS Code
body: <p>As a Windows systems admin, I use PowerShell quite a lot. With the release of PS Core, and the implication that the ISE is dead, I've started to try to use VS Code as my day to day tool. One feature I'm missing from ISE is the ability to swap between the editor and the terminal in fullscreen. I usually kept ISE open and maximized, and used Ctrl+R to swap between editor and terminal as needed. I haven't found a way to maximize the terminal, and swap easily between terminal and editor. I know I can make the terminal take up most of the screen, but a) this still leaves about 2 lines of editor open at the top, and b) there doesn't seem to be an easy way to then maximize the editor. Is there a way to minic the ISE behaviour that I haven't found yet?</p>
