Not in the preview window.  If you are viewing a message in the  
preview window, and click within the preview window area, then hit the  
down arrow key, you are moved to the next email message.  Hitting the  
page down key, you are taken to the last email shown on your screen.  
If you hit end, then you are taken to your last email.  You can, or at  
least I can, only move within the preview window, by cicking on the  
scroll bar.  Of course, double-clicking on the message and having that  
as the main focus, enables you to scroll by any method.

I have this behavior with Chrome and IE-11, and on a MAC using Safari.

Please know that I am only asking to try to better explain to people  
how to better use the horde webmail system versus what most used to  
use in Outlook.
