I use Oracle’s VirtualBox on my employer issued laptop. I’ve vented on Twitter about my frustrations with the product.
One such frustration, one which nagged me slightly below my “drop everything and fix it” threshold, was the inability to make use of the right Control key on the laptop and external keyboards. When I issued any key chord relying on the control key, nothing happened.
This morning my frustration boiled over to the point where I banged on the malfunctioning Control key repeatedly. VirtualBox popped up a dialog box reminding me of its role as the “Host” key. The metaphorical light bulb over my head suddenly illuminated.
I switched back to the host OS, Windows 7. In the Oracle VirtualBox window I selected
Preferences from the menu. Select
Input, and then the
Virtual Machine tab. At the
Host Key Combination line, erase
Right Ctrl and input a new one. For reasons yet investigated, only modifier keys are available. I chose a key combination unlikely in my Emacs config –
Right-Shift + Right-Ctrl + Alt.
The setting takes effect immediately without having to restart the guest virtual machine.
