#85 Clicking on error breaks key bindings
Clicking on a compiler error in the Compiler Error
panel highlights the corresponding line in the source
and sends the focus back to the DefinitionsPane, but it
appears to break key bindings-- arrow keys don't work,
nor does backspace/delete, etc. It seems like all
configurable key bindings are broken (though F5
works?), while most letter keys work.
Possibly an issue with the KeyBindingManager?

This turned out to be because the KeyBindingManager was
calling actionPerformed with a null ActionEvent. For our
actions, this isn't a problem, but for default ones (like
the arrow keys), no source component could be found, so
nothing happened. Instead, we now trigger an ActionEvent
with SwingUtilities.notifyAction().
