I reproduced this with a newly created user on my Debian computer where
I installed hydra from Gnu Elpa, loaded the files, and tried the recipe.

As far as I understand the definition of `defhydra', the example won't
do what the OP expects unless you additionally eval

  (global-set-key [f2] 'hydra-zoom/body)

Without that, the hydra hinting kicks in only after you have hit another
hydra key after hitting the prefix key.
