Keyboard shortcut to switch between browser tabs?

Because, dear readers, you have already been saving my life with your
tips and tricks and
application
recommendations, I'm going to get you to solve all of my problems! :) Here's my next question:

Does anyone know of a browser or browsers that have keyboard shortcuts for switching between tabs? I keep instinctively hitting command-arrow key thinking that it *ought* to switch tabs but alas, my Titanium beauty comes back with a blank stare. Again, thanks in advance...
