[Users] space bar

[Scott Lair]

Hello,

Using version 3.17.8. 

When reading an email the space bar scrolls the email by page and then
goes to the next unread when it hits the bottom.  Is there a way to
change the space bar to stay at the bottom of the current email and not
advance to the next? 

Couldn't find anything in the docs or the rc file.

thanks,

Scott
