Is there a way to reset search in Mail? I'm not sure how everyone is doing this. But I do roughly 20-30 mail searches a day. 

But when the search is done and now I want to see the top of my most recent email (for new emails and whatnot). How do I get there?

There's no keyboard shortcut to do this. And if I were to do this manually I have to press the X in the search field. Scroll the email list to the to top by using the scroll bar. It's really cumbersome.
I hope someone comes up with something better than this, but…


X-out the search - this awkwardly leaves you in the now empty search box rather than in the mail list.
Select any mail in the list. [Or hit Tab until you get back into the list. Depending on how you have your tabbing set up that could be three presses, or about 10:\ ]
Press Home [or Fn/Left Arrow if you don't have a dedicated Home key]
Select the top mail.


Basically, with this method all you're gaining is the Home key-press to get you back to the top. The rest is still very manual.
