This is probably one of those things I should be able to figure out.  In Sonar X3d I went to preferences/keyboard shortcuts so I could unbind the O key to avoid accidentally entering offset mode.  This binding is one of the default behaviors in Sonar.  However, I can't seem to unbind this, or any of the default bindings.  I have set up some bindings myself, and can see the links and can unbind them.  But it appears the standard key bindings (e.g., D for dock, I for inspector, O for offset mode) are not available for editing.  Is this true, or am I just missing something?
 
Thanks.

Hi Neirbod,
 
In Preferences - Keybindings there is a function to "Do Nothing, use to block pre-defined accelerators" in the keybindings list. Search "Do Nothing" and bind "O" to that function and it will block this from the built in Sonar accelerators. 
 
Hope this helps.

Perfect, thanks!
