Support a non-modifier

[statico]

Right now you can bind keys with modifiers easily:

k.down('ctrl shift q', ...)

It would be awesome if I coud bind keys without modifiers:

k.down('plain q', ...)

I'm not sure if plain is the right term. unmodified seems too verbose. :)

Interesting! And potentially very useful. (: I'll keep this in mind. Again, thanks for your feedback!

Now by default the key is bound without modifiers if none are specified.
