emacs elisp (other-window 0)

Question

I try to write a hydra function to switch windows. Basically I want that C-x o takes me to the other window, and then "o" will cycle through all the windows. So I put in .emacs

(global-set-key
   (kbd "C-x o")
   (defhydra hydra-other-window (:pre (other-window 1))
     "hydra other window"
     ("o" (other-window 1) "Next window")))

It does not work. C-x o does take me to the other window, but press "o" does nothing. However if I change 1 in the last line to 0, it works as expected. It is quite surprising because according the documentation, (other-window 0) will just select in the current window. Is there a good explanation for this? Any help will be appreciated.

You can use a simpler code:

(defhydra hydra-other-window (global-map "C-x")
  "hydra other window"
  ("o" (other-window 1) "Next window"))

Will C-x 2 etc work as usual after your modification? – user3208 Dec 07 '15 at 15:40
I tested your code. It works great! Thanks a lot. Do you have idea why in my original code, the second "1" needs to be "0"? – user3208 Dec 07 '15 at 16:29

Your original code calls `other-window` twice. You want to call it only once. – abo-abo Dec 07 '15 at 21:19
