Terminal stty shortcut
The command:

stty intr ^i


works exactly the same way on MacOS X as on Linux. Please note here ^i
are 2 characters and not a tab.

On the other hand, the command:

stty brkint ^i


replies:

stty: illegal option -- ^i


because brkint is a boolean option to stty and not one with any other following value, and because ^i considered alone is not a valid option to stty.
