Now I have another key binding issue. If I have an assigned binding with: Key B A M Music-Next
It call the function Music-Next when I press Alt+B. That work fine. If I remove it with Key B A M - That work fine too, Alt+B is doing nothing, and when in Ardour I can use Alt+B to fire and close its big clock. But if I want to remove it only when a window of class Ardour have the focus and I run Key B A M Music-Next Key (Ardour) B W M - it do nothing and Alt+B call Music-Next in any case, even when Ardour have the focus. I try the same thing with the name, class and resource of an urxvt term with the same result: the binding is not removed when the window have the focus. Same result with Key (Ardour) B A M - Also, I try with fvwm-2.6.5, and the problem is different, I must use function " ", the binding is removed when in Ardour, but Ardour's own function is not restored. This was working in 2007: https://mail.gna.org/public/fvwm-crystal-users/2007-03/msg00006.html Dominique
