Page Up/Down Issues With Emacs in Terminal

[Brandeis King]

Hi,

When I launch emacs in a (zsh) terminal with the no window system option, 
pressing the keys "page-up" and "page-down" results in emacs writing "5~" and 
"6~" respectively to the buffer and then changing to the previous/next buffer 
depending on which button is pressed. 

How can I configure emacs and/or the (zsh) terminal to scroll the page when 
page up/down is pressed as emacs does in a non-terminal instance? Thanks.

Best,
Brandeis
