Keyboard Navigation

Any keyboard navigation would be a godsend. Tab has inconsistent and (undocumented, as far as I know) behavior depending on the field or time of day. If I could fill fields or select things without clicking and dragging everything, or navigating menus by mouse, I would be so happy. I'm a 23 year-old with steady nerves and a gaming mouse tuned for middle-low DPI and click/release sensitivity set way down, and I still frequently mis-drag fields into the wrong places or create accidental hierarchies of completely unrelated things because I let go too early or it hadn't registered the full drag yet. I know colleagues who use the touchpads on their laptops for this, and the user experience is a nightmare.
