Yeah I know the tutorial covers the basics of any kind of plugin.
The problem is that handling the keyboard device seems to be a bit more complicated than having 2 color values. I know that the same concepts apply no matter what your plugin does but after looking at the standard mouse and keyboard plugin, I don't have the skill to do it from scratch, so I'd like to modify the standard plugin and add an expression to retrieve which key is pressed. (Even that I'll have to dig the internet to find out how to do it, I'm no programmer
The problem is that I can't build the plugin, some things must have changed, for example, there's no action/condition/expression files, they're all in the main.cpp.
