One nice interactive way is with the Macro Stepper feature in DrRacket,
which is easy to use once you know the button to start it.
Sometimes it helps to copy, into a new file, the minimal usage of
a macro you're interested in, and just expand that.
Also:
I always try to understand things from the bottom up.
How can I see the expansion of things like (match ...)?
More generally, how do Racket developers look at the internal forms of
programs?
