What are the host and home keys of virtualbox?

There is a HOME button in the virtualbox. Note that this HOME button is not necessarily the HOME on the keyboard, but a set key. The default right CTRL is the so-called HOME. Sometimes I don’t know how to switch back or find it. If you don’t reach the control bar, you can press the shortcut switch. The shortcut keys are Ctrl+F on the right to switch to full-screen mode, Ctrl+L on the right to switch to seamless mode, and Ctrl+C on the right to switch to proportional mode. Menu The display is to press the right Ctrl+Home key, the holt key is the right Ctrl key
