[TxMt] cursor page up

[Ryan Schmidt]

Apple HI behavior regarding this point is very deliberate (not lazy)  
and is clearly defined. Having used and written software for Macs since  
1990 I can assure you of this.

Pressing page-up scrolls up one window-full without moving the  
insertion point. Similarly for page-down. Home scrolls to the very top,  
without moving the insertion point. Similarly for End. (In 1.0.2b8 Home  
and End behave wrong.)

The relevant documentation (which also lists many other standard  
keyboard navigation shortcuts to do the other things you want to do) is  
here:
