+ THIS CODE SUCKS.
+
+we need:
+ - contexts that aren't compared as strings,
+ - maybe a lookup "device,key,flags" -> actions? (lazy validation, on bindAction)
+ - devices as ids
+ - seperate native from python keys? (currently, if an action wasn't found, it's ignored.)
+
+Sorry. I spent 3 days on thinking how this could be made better, and it just DID NOT WORKED OUT.
+
+If you have a better idea, please tell me.
