This is the type of weird stuff you can do in Linux.

The short answer is you combine
http://kollerat.com/cms/index.php/Allgemein/Software/Control-VLC-via-global-hotkeys-xbindkeys-under-Linux.html
with
http://live.gnome.org/Accessibility/GetInvolved

xbindkeys allows to run a special program when you press a specific
key/key combination.
The GNOME Accessibility API allows to send easily events to running
programs. I do not have a link to sample code; if you can search a bit
you should be able to find a small Python snippet that sends events to
specific windows. As a hint, look at dogtail,
https://fedorahosted.org/dogtail/ the software testing tool. It does
what you want in terms of controlling an application in a
comprehensive way. What you need to write is a small Python program,
'send_event_to_gedit.py', which would take as parameters 'pgup',
'pgdown', etc.
Dogtail creates a special script to control applications; you run
dogtail and you focus it on your gedit. Press PgUp/PgDown, etc and
work your way from the instructions it creates for you.

Hope this helps,
