MATE: Set global Emacs key bindings

This is by far (well maybe the cursor shape customization goes head to head with this...) that I have to setup no matter what on any box I get my hands on...
But, it seems like the new MATE version doesn't honour the way I've set this up on the previous Linux Mint LTS.
On Linux Mint 17, running MATE (duh!) I've used this:

gsettings set org.mate.interface gtk-key-theme "Emacs"
