I found this which might also be of use: (looks like what I need to do, mouse hover, mouse click do some logic, mouse click to select and pick up an object and move it about)
One of the problems with examples, as a noob, is what sequence of events I need to do to get something up and running. I see things I want to do but can’t achieve them, and have to keep closing my project, open a sample, go back to my project, nope doesn’t work, close, open, look, close, open, nope, etc and it gets a bit frustrating. So I go off and do something else, hoping I will pick it up later.
I guess that is where this helpful forum comes in 
Fen, I was actually thinking of applying the web/js/html plugin vaquoleUI as a hud and would be ideal for what I want to do, but I couldn’t work out how to get that running, again as a noob many examples are difficult to achieve without a full start to end detailed explanation. I will have to revisit that one when I know a bit more.
Cheers for the replies.
