Please post separate bugs in separate threads. This thread is not about $hotlink(event) or $mouse.key. On a sidenote, I can't reproduce either of your claims, which is all the more reason to start a separate thread with proper reproduction steps so it can have a proper conversation about whether your report is actually valid, and, if so, what it affects and what can be done. I should reiterate that this thread is not the proper place for such a discussion.
