Customizing the Vero 4k remote

I have found a lot of posts on how to customize different remotes, but I cannot find definitive instructions in either the forum or wiki on where to make changes to what file in order to customize the Vero 4k remote.

Is there a guide I have missed somewhere?

The easiest way is to use the Keymap Editor add-on. See https://kodi.wiki/view/Add-on:Keymap_Editor.
