Just a couple of quick Mac tips. First, many programs support using Command-<number> to choose that tab in the program. Some programs are explicit about it and might show the shortcut, like iTerm 2, but this will work in all major browsers I have tried as well as Sublime Text.
Also, most times when you are using a key combination to cycle through something (like tabs in a browser or the Command-Tab program switcher), using Shift will reverse the direction. So if you go past your intended target, you can often go backwards instead of cycling all the way back through.
