General help

I think the problem here is that a label is immediately visible on a page - so automatic completion would happen immediately - so for example if there is an embedded video then the person wouldn't need to watch it. I don't know the code could be made to specify that they had to click on the video to play it for the automatic completion to work (and then what if a label only had text, or an image - how would automatic completion work then?) Fortunately I am not a coder so hopefully someone else will be able to solve this problem
