I think it's OK not to require a complete mouse emulation (i.e. pixel
level) since this best fits in the lower OS layer.

I think there should be a requirement for keyboard support of Web UA
specific mouse level events (e.g. things specified in HTML/script,
like click for keypress, mouseover effect for traversal focus, etc).
