While it is easy to create a keyboard shortcut for most many bar items, one seems to resist this attempt at increasing productivity. Creating a shortcut for the File, Tag... menu item seems to just not work. The problem seems to lie in the little color circles that accompany the item. You can use them to assign some favorite tags to files easily, as long as you use the cursor. But with a little trick, you can get the File, Tag... menu item to work with a keyboard shortcut. Then you can apply any tag using only the keyboard.
