relative positional Expression (next|previous) <css expression> [from <expression>] [within <expression>] [with wrapping]
Relative positional expressions allow you to select an element relative to another element in the DOM, using the
next and previous keywords. The command will scan forward (next) or backwards (previous) in a linear depth-first
walk over the DOM, including elements adjacent to parent elements.
You can use the from clause to start the linear forward search from another element. The default element to start
the search from is the current element that the script is on.
You can use the within clause to restrict the search to a given subset of the DOM. The default is the entire document.
You can have the search wrap around by adding the with wrapping clause at the end of the expression.
These expressions can be used, for example, to create a custom focus ring.
