+The @code{other-window} command will normally only switch to the next
+window in the current frame (unless otherwise configured). If you
+work in a multi-frame environment and you want windows in all frames
+to be part of the cycle, you can rebind @kbd{C-x o} to the
+@code{next-multiframe-window} command.
