I could do that, but in the interests of the struggle against nescience, in all of its rampant forms, please read on.

you could add a OneLook button to your toolbar, right up there with the Address and Go buttons. then you could just click OneLook and paste a word into the OneLook search box and you would save yourself (and myself) the all the time it takes to ask (and answer) this kind of request. If you don't know how to do this (it's really simple) I could post the instructions right here. (this is Miscellany, isn't it?!)

you can, of course, do this with any site you use so often that even using a bookmark seems bothersome.
I have buttons for OneLook, OED, and (wait for it) wwftd on my toolbar. (there, now this is almost an actual word post.) all browsers give you similar customizing features.

oh, here's the link for aetataureate

but if you just want to skip the whole thing, mav is pretty much there.
