Hi,

Zoiks!  It appears that feature was removed when I added all the fancy 
mouse interactions and rebuilt the automatic UML diagram generator and 
never got put back in.

I've checked in a small change adding a keybinding and context menu for 
jumping from a node to a class.

The original layout engine was a bit lame, and only handled 3 levels. 
The new layout engine is much better, but the generator is still only 
does the 3 levels after I moved the code around.  I don't think it would 
be hard to get this fixed up, but no one has taken the time to do it.  I 
do think this is a big missing feature.

Or rather, do you just want to merge two graphs together?  You can Kill 
and Yank nodes around.  I hadn't tried doing so between diagrams.  I do 
know you can "copy" a class out of a source file and "yank" it into  a 
graph.  That's pretty cool to do.
