The last menu items of the 窶弩indows窶 menu change according to the titles of the open windows. Thus, if e.g., you have three open windows called 窶弩indow 1窶, 窶弩indow 2窶 and 窶弩indow 3窶, then you will find three menu items too with the same names. By selecting say 窶弩indow 2窶 you make this window the active and frontmost window.
