specific keyboard command needed
When a window pops up with multiple buttons such as "save", "cancel", and "don't save", or when a program crashes and the options are "close" and "reopen" and something else, how in the world do I move between those options without using the mouse? I know in Windows you just tab through them, but I cannot figure it out on OS X. Any help would be appreciated, as I just probably spent more time writing this email than I will save by learning the command.
