SCINTILLANOTIFICATION.KEY doesn't seem to be firing at all (I've read https://sourceforge.net/p/npppythonscript/discussion/1188886/thread/bd53ce2f/?limit=25#0834 this thread and STILL can't figure out when it's supposed to fire, but that's a question for another day). .CHARADDED doesn't fire either, I guess because the Ctrl prevents the Enter keypress from inserting anything.
How can I capture Ctrl+Enter?
edit: Crap, how did this end up in Script Showcase? I'm not used to the Sourceforge forum interface. I'm going to crosspost this to the Help forum, please delete this thread.
