Hello, Nirsul

When I checked for the Y key, it got listed as NonSacredTool. I don´t know what that means, but it sure is different from the RepeatLast action the G key is mapped to. Which would suggest you´ve been playing a lot with the HotKey Editor.

In any case regarding your trouble with the Q key, check the pic for the command you need. Remember to map the SelectMaskToolMarkingMenuPopDown command to the G key release.

Hope this helps,
