For me, skittering is letting my eyes go where they want to in a rapid fashion. Kind of like REM except I'm reading and not sleeping.

Turns out I have been doing this already, especially with newpapers. My eyes flit about the pages how ever they want to. Usually in a "Z" shape fashion.

What kills me is that a word will jump out at me, but my eyes will have already moved on. So then I get this word stuck in my head that interests me and I have no idea where on the page it came from. ::sigh::

Since I am new to PR, I can't really comment on using skittering to activate, just skittering to find what interests me in a hurry.
