Single Page Up and Down.

[KoolStar]

I had been looking for the longest time how to move one screen up or one screen down in any document or webpage. I tried the Command + Up Arrow and that took me to the beginning or end of the document. Well I just discovered that SPACE in Safari will go one screen length down in the web page. To go back up one screen length you can use Shift + SPACE. Just thought that I would share my findings.
