"Cycle Through Windows" Menu Item is Missing I recently noticed that the normal cycle through windows command was not working in many of my applications — Terminal is about the only one left that would work. I went to go check, and the Cycle Through Windows item in the Window menu is gone in multiple applications. 

I attempted to assign a cycle command ( Command + `, as is normal ) via the Keyboard preference pane (in some vain hope that the missing menu item would have just been invisible), but that did not work either. 

I am completely at a loss here, especially as cycling through open windows is part of my normal workflow.
Most applications have never had a menu item for it. I don't know why Finder and Terminal do though.

⌘` should cycle through windows by default, but if it doesn't, check if the shortcut has been disabled or changed in System Preferences.
