In Windows, it is possible to set pressing Ctrl to display the current location of the mouse pointer, as per this tutorial.
Is there a way of setting a key or key combination to perform the same action in Ubuntu?
Open Terminal and run the following command
gsettings set org.gnome.settings-daemon.peripherals.mouse locate-pointer true
Now if you press ctrl the pointer should be highlighted.
If anybody still needs it.
It is possible to find this option in the GNOME Tweaks, so go to
Keyboard & Mouse -> Pointer Location
and turn it on/off.
