When using virtual machines to be able to have different operating systems within a team, one of the stars is VirtualBox. It is a free software from Oracle, through which it is possible to obtain for free a multitude of the features that other programs offer for a fee, which is a great success within the virtualization landscape.
However, despite the fact that from time to time they are updated and new fully compatible operating systems are incorporated, depending on the system to be installed, the complete integration of the mouse may not be supported, being necessary to capture it in order to use it. Once captured, If you want to return to the equipment, you must configure a host or host key, which when pressed will regain control, so we are going to show you how you can customize this key.
So you can change the host or host key in VirtualBox
As we mentioned, this host key or host this is a way to exit the guest system to return to the original, so it is quite important. In Windows, it is common to see the default key Right CTRL as configured by default to be able to escape, but the truth is that you can configure the key you want.
To do this, you must first go to "File" at the top and then from the drop-down menu, select the option "Preferences ...". Then, within the configuration menu, you must choose the section called "Entrance" on the left side, and then hover over the field named "Host Key Combination", where you will only have to directly press on the keyboard the key (or combination) that you want to set as host and, as soon as you save the changes, it will start to be used.
Once the change is made, you will see how when capturing the mouse again a notification appears in which the new host key is remembered. If you want to leave and return to your computer at any time, you just have to press it.
