October 29, 201411 yr Hello Sensuki, Thank you for your posting and video. We are aware of a few of these issues with the action bar hotkeys. Our UI programmer is working to have these resolved soon. I will make sure to link this issue in the known issues list for others to see as well. Thank you for your support!
