[racket] Single Step evaluation in Racket

Hi.

I just wanted to know the short-cut to do the *single step evaluation* in
racket.

I want to know if there is anything analogous to adding *watches* in *Turbo
C* for particular variable (to see how they change) and then hit *F7* key
to implement line by line execution.

Is there a way to do this racket?


Best,
Zeek
