Is there a shortcut to see how much battery you have? and how much your volume is?

Instead of dragging the cursor all the way across the screen to hover it on top of the small tiny icon, is there shortkey that i can use to make it show the volume level and the battery level?

I never used this but read it somewhere so tell us if it works:

There does not seem to be any keyboard shortcut for the battery meter. However, Windows 7 has a super-useful Windows Mobility Center dialog that is enabled on laptops. It displays the battery meter and a few other statuses.
The keyboard shortcut to bring up this dialog is Win+X. Press Esc or Win+X to dismiss the dialog once you have noted your battery level.
