I have an apple usb keybord for my ubuntu 12.04. I remaped command left key to control for convenience. And now I switch between apps with alt-tab and between tabs within one app with ctrl-tab. It's normal but not comfortable and painless.
It would be ideally to remap shortcuts as opposite: ctrl+tab – switching between apps, alt+tab – between tabs. Can I do it? xmodmap?
UPDATE: here is a screenshot of settings which I apply, restarted but it hasn't changed:

You can change your Keyboard Settings from System >> Keyboard >> Shortcuts.
Under Navigation, you should see "Switch Application". You can click it and set the new short cut as you want. Hope it helps.
