This doesn't quite work because w is a Window, not a WindowSet. However, the following does appear to do the right thing
action <- runQuery (doShift "mail") w
windows (appEndo action)
It still seems a bit on the convoluted side. Is there a way of getting an appropriate WindowSet from the w :: Window that I do have?
