Thanks for the tip. That helps.
Depending on how you implement the input process it may be really hard to expose the functionality but it will really be nice for newbie to have a way to do a "describe-key" type query! Another thing that maybe useful is a way to automatically query and then display a key binding map sorted both by key names and by function names? If I can get to them via the API I'll be more than happy to write a plug-in to do this.
Thanks for a great piece of software. After all these years you may convince me to switch from emacs!
