PageDown in AS400 Terminal Window

Good day,

I am accessing an AS400 application. Most keys work fine [as expected]; however, when I send PageDown, it only moves the cursor down. From my keyboard I can PageDown or FN+arrow down to go to next page. Is there a specific command other than PageDown that I can send to activate the PageDown feature?

Also, in regards to Terminal Connection and setup, I am unsure where to find the original Terminal Connection. I inherited this process. When I click on configure connection, I get a message that indicates Connection is already setup to an existing connection. Any help is appreciated.

are u using page down hotkey or send control key activity ?
