add-application-window

Arguments: window &optional (key (name window)) (subkey (default-application-window-subkey))always

Caches a window so that it can later be retrieved by find-application-window using the specified key (which defaults to the name of the window being cached)) and the specified subkey (which defaults to the value returned by default-application-window-subkey).

Typically you would accept the default values for key and subkey, and later pass only the name of the window to find-application-window. But these arguments could be any two values at all, as long as you pass values that are eq to them to find-application-window to find this window.

If always is true, then the specified window will replace any existing window that has the same key and subkey in the cache of all application windows. If always is nil, then the specified window is not added to the cache of all application windows if there is already a window there that has the same key and subkey. The default is nil.
