Visual Studio Code has a hotkey combination to split the current window to 2 or 3 panes:
"key": "ctrl + \", "command": "workbench.action.splitEditor"
Unfortunately, I can't find a way to switch between such panes without the mouse. My old habit to use F6 does not work either.
Is it supported in Visual Studio Code editor or not?

For Windows: Ctrl+1, Ctrl+2 and Ctrl+3.
For Mac: Cmd+1, Cmd+2 and Cmd+3.
There is no circular switch between panes, similar to what Ctrl+tabs does for files, though.
