Ubuntu – Virtual machine, mouse cursor only works within the box

virtualbox

I am experimenting with virtual box. One of my problems is that the mouse cursor only works within the box. How can I make it work both with the actual OS too and the virtual box at the same time?

Right CTRL key to release the mouse and keyboard.

Install guest additions for transitions without manually releasing the keyboard/mouse.
