When reading an email message you can press:

"T" to move to the top of a message
"B" to move to the bottom of a message
The "Spacebar" moves you incrementally down the bottom of a message

Anyone know if there is a shortcut to move you incrementally to the top of a message (opposite function of the spacebar)?

Thanks in advanced!

Shift Space

There are more, look at Stinsonddogs Tips if you have not. Link in my signature.

Shift + Space

Oops, looks like I was too late.
