Add a new command to focus link.

[potpath]

This would fix #2188 and #3055.

Thanks, @potpath.

I'm not sure we should do this in this way.

You care about focusing links. Others care about hovering, or unhovering, or yanking link text, or whatever.

We would end up with too many new commands. I'd rather consider doing this like this...

map A LinkHints.activateMode
map B LinkHints.activateMode action=focus
map C LinkHints.activateMode action=hover
map D LinkHints.activateMode action=unhover
map E LinkHints.activateMode action=yank-text

Then, we just document the variations on the Wiki, and don't pollute the help page.

How about this #3098?

Closing, see #3097 instead.
