Under the "Save for Web" settings, when I hit tab on my keyboard to move the cursor to the "Colors" setting, the cursor automatically tabs over to the "Web Snap" setting instead. When I hit shift + tab to move backwards it automatically jumps forward again. The only way I can get to the "Colors" setting is with my mouse. This behavior is new to Photoshop CC 2015.1.2. Never had this problem before and it's an integral part of my workflow.
