Hi Working in GUI is nice, I only like using shift+Delete control+Insert shift+Insert shortcuts for working with clipboard and currently it does not work in XQuery window in BaseX GUI See http://en.wikipedia.org/wiki/Cut,_copy,_and_paste#Common_keyboard_shortcuts
I am working on MS Windows.
You see, I do care about your wish list not to let it empty for too long time "-).
