Is it possible to navigate between panels using keystrokes?

I spend a great deal of time keywording. I go to the Keywords panel, search for the keyword in my list, press the arrow buttons in the panel until it gets to the correct keyword, then I press Return to apply the keyword. That part works great. But then to apply a keyword to the next image I have to click on the image, then click back to the keywords panel and repeat the process of looking for the corect keyword. Is there any way to switch the focus from one panel to another, just by using keystrokes? I've checked several different versions of Bridge and can't find anything that would allow this. Am I missing something?
