Your X server is set up so that the NumLock key is mapped to Mod2.  I
learned by accident that Mod2 is actually quite useful.  Mod2-click on a
cell selects all cells of that type in the current notebook.  This is an
easy way to delete all the graphics cells and output cells in a notebook to
reduce file size.  An annoying aspect is that Mod2-click means press
NumLock, click, then press NumLock again to turn it off.  You should be able
to map a different key to Mod2 using xmodmap.  Remapping modifier keys in X
is awfully annoying, though.  I recommend xkeycaps
(http://www.jwz.org/xkeycaps/).
