Home & End keys don't work

The home & end keys do not move the cursor to the home or end of line... I have to use control--> or <-- . I have searched the web and so far have not found any fix or explanation for this behavior on the Apple/Mac keyboard... closest I have found is http://www.geekguides.co.uk/86/how-to-make-the-home-end-keys-on-a-mac-keyboard-work-like-home-end-keys/.

I'm also looking for the Insert key... would like to use keyboard short cuts for copy and paste... yeah, I'm an old DOS guy...
