No, but you could have done the research yourself. If you look at any clientside add-on that includes a GUI then check how it binds a key, you'd have never had to make a topic. It's okay that you did though, just don't give people stuff that are trying to help you.
Also, there are better ways to do this. You'd probably want to add an entry to the controls section in options.
$remapDivision[$remapCount]="IRC";
$remapName[$remapCount]="Toggle";
$remapCmd[$remapCount]="ToggleIRC";
$remapCount++;
You could probably pair this with GlobalActionMap.bind() to set a default value, but I've never actually tried that.
