Alt + mouseclicks or -movements doesn't work properly

[Nikolaus Waxweiler]

Hi,
this is a strange one. According to the GWorkspace guide, 
ctrl+doubleclick on a folder (in that "folder -> folder -> file" view) 
is supposed to open that folder in a new window, which it doesn't. 
Alt-dragging to copy a file also doesn't work, whereas ctrl-dragging 
to link one does. In Gorm, pressing alt (or alt-shift) and dragging 
the handle of an object is supposed to create a matrix of them. 
However, it looks like the alt-key is silently ignored and the object 
is just resized as usual. What does work is ctrl-dragging an object to 
the instantiated-objects-panel to set connections. So, uh, am I doing 
something wrong or is this a bug?

On a sidenote: AppKit/NSResponder.h tells me that 
'deleteWordBackward:' is implemented, but the source and a beeping 
keybinding say otherwise. What gives?

Versions:

the libart backend, doesn't work with back-xlib either), 
gnustep-base-1.11.2_1, gnustep-gui-0.10.2_2, gnustep-make-1.11.2_1, 
WindowMaker 0.92 (tested it with twm, same symptoms)
