Version 2.3.1 it seems that the [pig] + [@] shortcut to unpatch does not work.  Not just the shortcut but also the [Unpatch @] button.
 
More precisely, it does work for a fixture with user number 1 that is patched to dmx 1.  However, it does not work with fixtures with other user numbers (where it is patched is irrelevant).
 
An example for further convincing:
 
Let us patch 10 VL3500 Spots.  
 
VL3500S 1 > 10 @ 1 
 
Now we have successfully patched 10 fixtures.  Note that our user numbers are 1 thru 10.  
 
Now we shall unpatch fixture 3.  
 
[pig] 3 [@] 3 
 
This did not unpatch the fixture.
 
Next try to unpatch fixture 1.
 
[pig] 1 [@] 1 
 
Fixture 1 is unpatched.
 
q.e.d
