Indeed. When I asked about this on the Emacs Help list a few days
ago, Marcin Borkowski pointed that out, and indeed, as I mentioned
there, following this suggestion I tried:

  (defhydra hydra-zoom ()
    "zoom"
    ("g" text-scale-increase "in")
    ("l" text-scale-decrease "out"))

  (global-set-key (kbd "<f2>") 'hydra-zoom/body)

and this does work just fine. :)

Sorry. I should have mentioned that in this bug report.

So this bug report is about the

  (defhydra hydra-zoom (global-map "<f2>") ... )

form not working and/or about the doc where this is used as the
first example.
