and stripped from the internal buffer string and the value assigned to
`state.count`. Then `lousy.bind.hit()` is re-called with the modified
buffer string & original modifier state.
#### Example binding
lousy.bind.key({}, "%", function (w, state)
w:scroll{ ypct = state.count }
end, { count = 0 })
This binding demonstrates several concepts. Firstly that you are able to
specify per-binding default values of `count`. In this case if the user
types `"%"` the document will be scrolled vertically to `0%` (the top).
If the user types `"100%"` then the document will be scrolled to `100%`
(the bottom). All without the need to use `lousy.bind.buf` bindings
everywhere and or using a `^(%d*)` pattern prefix on every binding which
would like to make use of the `[count]` syntax.]],
