While, I'm trying to adjust myself to using Visual Studio Code, I found it quite annoying that there isn't a shortcut to switch focus between the editor and the integrated terminal. For a guy, like me, who makes use of the keyboard all the time, that's pretty important.

I did some research and found a way on how to do it. Just type Ctrl+Shift+P and type Open Keyboard Shortcuts and add these lines:

[
    {"key": "ctrl+`", "command":"workbench.action.terminal.focus"},
    {"key": "ctrl+`", "command":"workbench.action.focusActiveEditorGroup", "when": "terminalFocus"},
]

Save the file and now, you'll be able to switch between the two by pressing Ctrl+` keys.

Hope you found this tip useful!
