Thanks, I'll be sure to fix that.

Currently, calling top-level lisp functions from click events is a bit 
of a hack. Pages still run Javascript by default for any inlined script 
(oncommand, onclick, etc handlers) and I haven't looked into trying to 
hook that or anything. So instead, if the function is undefined, it 
looks whether there's a lisp version, and calls that.

Strictly speaking though, yes, it's possible to call arbitrary CL from 
JS. But it requires creating a component from the JS and invoking its 
"evaluate" function (not demonstrated in this sample).

MPL almost certainly.
