Hello, I'm new to visionegg (and computer programming generally!), so apologies for the simplicity of this query! I've designed a simple stimulus that I'd like to run every time I press a key, returning to a particular screen in between presentations. I understand that I can do this using run_forever and multiple go loops, but I can't seem to figure it out in practice. I just wondered if anyone had any sample code that they wouldn't mind me taking a look at, so that I could get my head around how this works? Many thanks in advance! Roger
