Sounds dangerous but might work.

I think it would probably be appropriate to make this optional initially
as well.

Hmm, do you mean that? Or that the string of the characters will be passed?
I.e. one by one or all the so-far typed ones?

Should be showing more than one.

This is the part that sounds most awkward. Not the not-automatically-moving
but rather, the two spaces. 

Modes usually use the same key for entering and exiting.

Would ESC work for exit also?

This I quite like.

Also needs a binding to go to the next search result in a list.

We'll need to fork things anyway for the bindings...
That's why having them modular and optional is good.
