Disabling Control Key for mouse location

[Erol Akarsu]

I need to disable Control key to show mouse location on Gnome 3 on
Freebsd.. Currently, when I press Ctrl key, it shows me the location of
mouse that I want to disable. I am searching for this but not able to find
a solution

I need this Ctrl disabled because I am having difficulty in using Control-C
Control-V in VirtualBox installed on latest Freebsd system.

How can I do it?

Thanks
