Oh that abbreviationism of His Kennyness ... ;-) As ".w." is defined as (define-symbol-macro .w. (or (.window-cache self) (setf (.window-cache self) (upper self window)))) and swdw is defined as (defmacro swdw () '.w.) I am guessing that this stands for something like "symbol-w?-d?- window" but I may be simply going wild and crazy here (that being my standard ending for mails to Kenny as I have completely missed a fundamental concept in the past ;-) Thanks for enlightening me!
