Ask Gmail: "What emails have I had today?"

I have several filters in my Gmail account, which helps me control my email lists etc. The problem though is sometimes it can take a while to click on my filter folders (labels) to check my mail. Sometimes I just want to say, 'Show me mail I've got today'

Well it's as simple as this:

In the search box add:

Today being the 8th July 2007, it will show you mail up until your current time.

Simple, but then Google quite often works that way.
