[CW] Is there a method to learn how to send code with no transmitter?

[Bob Young]

OK, I'm out of the country and have been out for a while with no transmitter or antenna here.  I've learned all the characters with the G4FON online code trainer and now want to practice sending, I bought a key but of course have nothing to use it with here so is there an online trainer that lets you use a letter or something on the the computer keyboard to send to an online code trainer? With G4FON you have to use a key or something like that. I'm going back in a few months and will set my station back up and would like to be able to send at least decently when I start.
