+If @var{alist} contains a @code{mode} entry, its value is a major mode
+(a symbol) or a list of major modes.  If @var{alist} contains no
+@code{mode} entry, the current major mode of @var{buffer} is used.  A
+window is a candidate if it displays a buffer that derives from one of
+the given modes.
+
+The behaviour is also controlled by entries for
+@code{inhibit-same-window}, @code{reusable-frames} and
+@code{inhibit-switch-frame} as is done in the function
