254260 - Implement Opera's "Spatial Browsing"

Status: VERIFIED DUPLICATE of bug 67684

(Core :: DOM: UI Events & Focus Handling, enhancement)

Description

[Lukas Petrovicky (CZilla)]

User-Agent:       Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7) Gecko/20040803 Firefox/0.9.1+ (MOOX-AV)

Opera's "Spatial Browsing" is a feature that allows the user to navigate through
links in the order in what they APPEAR on the screen.

Let's have following layout:
Link1, Link2
Link3, Link4

We have Link1 selected and we press a shortcut to move DOWN. tabindex or other
indexes are then ignored and the browser imediately selects Link3, instead of
selecting Link2 which is a default behaviour.

This functionality is really uselful and I think we should implement this
spatial browsing at least for UP and DOWN directions.

Reproducible: Always

In Mozilla, F7 turns on caret browsing, which is very similar...

IMHO dupe of bug 67684 - Directional keyboard navigation needed (alt+shift+arrow?)
