CURSOR HELP
CENTRE CURSOR places the cursor on the centre  position.   CURSOR 
POSITION allows cursor coordinates to be edited.  UP CURSOR, DOWN 
CURSOR, LEFT CURSOR & RIGHT CURSOR do just that by one increment.
ZOOM MOUSE toggle converts mouse to pointed hand allow zooming in 
on areas by placing the mouse at the top left of the desired area 
depressing  the  mouse button and pulling a rubber box  over  the 
selected  zone.   If the [Shift] key is depressed zooming is  out 
rather than in.  DRAW MOUSE toggle makes a cross hair mouse  that 
draws  from the last defined point,  or just marks if [Shift]  is 
down.  ELASTIC  MOUSE allows drawing by holding the  left  button 
down and marking points with the right button.
