I am using Mac OS X 10.8.4 on a Macbook Pro and somehow alt-tab is switching between the applications from Dock. I would like alt-tab to work within RDP (Windows) only.

I don't know how (or if) did I enable that (i do not have KeyRemap4Mac or anything like that).

Is alt(option)-tab supposed to work as default?

Any ideas how I can disable this behaviour?

It sounds like you've managed to change your keyboard mappings. Assuming you haven't installed 3rd party mapping software, the quickest fix is to restore the mappings back to default.

SystemPreferences -> Keyboard -> Keyboard Shortcuts -> Keyboard & Text Input -> Restore Defaults

Most likely one of the "Move focus to X" options is set to alt-tab

  • Yes, thanks! I tried setting "option-tab" to some other shortcut and noticed I had at some point set it to some other obscure action. (sorry for the late reply, I somehow didn't get the StackExchange notifications and had just given up on it :P)

Also check if you don't have both keys swapped in System Preferences > Keyboard > Keyboard > Modifier Keys.
