Hy List,

This is not Orca problem, but my friend ask me a question, but I not 
known an useful answer. He don't found any keystroke in Openoffice.org 
Writer to jumps prewious and next page with a document with direct method.
Two time pageup presses jumps between pages, but have an easyest 
alternative keyboard method?
Anybody known a keystroke with this task? Ctrl+Pageup and Ctrl+Pagedown 
general keystroke is not working.
