It looks like you are doing the design part right -- having a stand-alone
function to deal with all the diff. widgets you want to handle.
The thing is, python is giving the widget to your handler as an argument.
Change the definition to:
"def sendkey( widget, data ):"
and you should be fine.
The 'data' argument is any data that you wanted the signal to pass to your
handler and is specified when you connect the handler to the signal.
