Some help in regards to Diplomacy just in case any one had issues like me.

1. Go to the top left of the screen and look for a spear with a flag on it.
(This is the last circle option listed as "Console commands").

*MAP SPOILER COMMAND*
2. Enter "fff" with no space before or behind it and click on the two arrows ">>".
(This will remove "Fog of War" so the whole map will now be visible).

3. Click on a settlement/region/capital of the faction you would like to fiddle with as the regions "menu" will appear.
(This is also known as the "Overview" tab/option of a region where all other settlements int he zone appear).

4. Click again on the little command box on the top left of the screen and enter for example "peace".
(This box/rectangle will be the console command text zone that appears once you click on the "Console Command" button).

With this comment, it goes against the devs command example of entering "peace2" or the like but I hope this worked as I had to find out myself like this since I didn't see any other good comments to help etc.

Happy gaming!
