As part of the big bug review for 16.04 LTS I have tested this on 15.10 and the bug is still there. I usually work around it by changing the HUD key combination to <alt>+<z>, but this might not work for someone who uses the HUD extensively (I do not).

I am always in an app (irssi in screen in terminator) where I press ALT+w sometimes, many times a day. Often I get the HUD popup and frantically stab escape or alt to get rid of it. I've always had it pop up in the past now and then but now it's many times a day.
