Not owning a magic mouse, I'm moving between spaces by using the combination ^+← and ^+→
Things worked properly until I have a virtualbox window being on full screen mode, which takes whole new space. The combination above keep moving spaces then it stops when the mouse (or keyboard?) get focus inside the virtualbox window.
I had to click outside the virtualbox window (by clicking on my 2nd monitor) then hover the mouse over the virtualbox window and re-apply key combination to move spaces.
So, is there a configuration of virtualbox or on macOS to keep moving smoothly between spaces even when there is a virtualbox space.

The same thing happens on i3wm, the mod+#number is captured by the box instead of the host. So Gonzalo Lucero's workaround helped!
