How do I remap my Ubuntu keyboard shortcuts to match OSX?

I'm using Ubuntu in VirtualBox on Mac. As I switch frequently, I would like to use the same shortcuts. Please, does anyone know how to have the same shortcuts on Ubuntu, as they are on Mac?

Specifically, I would like to Copy, Paste, Select All, ... work with Cmd+C, Cmd+V, Cmd+A, ... (even in terminal - no Ctrl+Shift, just Ctrl).

I tried to change Keyboard Layout to Apple Laptop, but that didn't help.

Searching in other questions I've found this tool to map the Ctrl to the Macbook key board CMD Left to do CMD + C or CMD + V or something else:

Install gnome-tweaks application:

sudo apt-get install gnome-tweaks

Open the application Applications -> Gnome Tweaks and map the CTRL to WIN(Same as CMD in Mac) doing this:

1. In the left vertical menu, select Keyboard
2. In the right hand panel click the Additional Layout Options button
3. In the list, expand Alt/Win key Behavior
4. Select the option Ctrl is mapped to Win and the usual Ctrl keys

Enjoy the CMD + C or CMD + V in your OSX VirtualBox using ubuntu-18 VM.
