set a (same) class to a next element using the class to find the first element

Hello,

I have a input field and a list. the input field contains script.
When the input field is changed, the list will shift the selected class to the next element. Snippet code example:

```

```
This isn't working. Due to the `from .selected`
my understanding from thr docs:

`(next|previous) [from ] [within ] [with wrapping]`

is that after the from an expression is allowed to defined a starting point other that `me` wich is the input field and not usable.
Also my understanding of expression can be anything as from the doc:
```
Others are a bit more exotic and, for example, make it easy to work with the DOM:

ID References: #foo
Class References: .tabs
Query References:

Start from the issue's hyperscript snippet and the documented `(next|previous) [from ] [within ]` syntax. Reproduce the `.selected` and `#selected` variants, then compare the expression and DOM-reference behavior; done means the documented syntax and a hyperscript way to identify or update the selected list item are clarified.
