Home, End, PageUp, PageDown, Delete?

On my MacBookPro I don't have the traditional navigation keys you have on a on Mac laptop.

I am missing:

Home, End, PageUp, PageDown and Delete.

Well, the MacBookPro does have a "delete" key, but that is really a PC "Backspace"

I found the following key combination's useful to emulate my missing navigation keys:

Mac Key	Windows Key
Command Down Arrow	MS Windows Delete
Delete	MS Windows Backspace
Command Left Arrow	Home
Command Left Arrow	End
Command Up Arrow	Page Up
Command Down Arrow	Page Down

Select Section:

Mac Key	Windows Key
Shift-Click	MS Windows Shift-Click

Select/Deselect Single:

Mac Key	Windows Key
Command-Click	MS Windows Ctrl-Click

Interesting... command right arrow does not work in Firefox.
But Option Right-Arrow does word right and Option Left-Arrow does word left...
