I would like to use showHint with multiple lists associated with different CTR-key. That is, CTRL-A to bring up list A and CTRL-B to bring up list B. Is this possible?
Looking at the “synonym” showHint example, I thought maybe I can detect what keys were pressed and switch the “comp” to point to different completion list. But I am unable to figure out a way to detect the keys pressed.
Does anyone know a way to accomplish this?
Thanks.

Yes. You can pass `showHint` a completion function to use, and bind different keys to different invocations of `showHint`.

Thanks, Marijn. How would I pass the “completion” function to showHint()? I tried cm.showHint(function () {…}) but the function didn’t get called. Could you give an example?

See [the documentation](http://codemirror.net/doc/manual.html#addon_show-hint), specifically the `hint` option.
