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.]],
