To find a region press <Cntl><f> opens a small window in which you start typing the name of the region for which you are searching. While you type you will get a list of the regions matching what you have typed up to that point. Once only one region is left the map navigates automatically to that region. Press <Enter> to remain in that region.
You cannot search for a city with <Cntl><f>, but you can use Google™ Maps of course
