Current Behavior

• Pressing Page Up button does not scroll up in the edit mode page.
• Pressing Page Down button does not scroll up in the edit mode page.

Expected Behaviour

• Pressing Page Up button scrolls up in the edit mode page.
• Pressing Page Down button scrolls down in the edit mode page.

When you switch to the edit/preview mode, Page down/Page up keys don't work.
Also the other cursor keys up and down don't work.
This happens with Firefox, Chrome and IE8.
Using IE8 Page down/Page up keys don't work in edit mode.

This worked in Confluence 3.5.
