In the meanwhile I found system preferences here
https://github.com/gnustep/apps-systempreferences/releases
and set the key modifiers to
First command: Left Meta
First Alternate: Left Alt
First Control: Left Control
but this made no difference. I still can't initiate drag operations in my apps
with Ctrl-Drag, neither under WindowMaker nor xfce. I instead get a context
menu. So the window managers obviously steal the key mouse event!? :-(
Anything I can do about that? Has anyone Gorm.app running under WindowMaker of
xfce?
Thanks,
Andreas
