My mouse dose not have a scroll wheel and the end and home keys are just a bit flakey .when hitting home it just dosent quite fit the screen the top module is sorta cut off at the top.. Arrow keys do nothing  , one would figure having focus and using the arrow keys one would be able scroll up and down, in fact a separate scroll bar should be added in the pro channel area. Without a mouse with a scroll wheel just makes it so much harder to use. The way I use it now is by collapsing each module .( Pita ) . 
 Also gotta see how to configure the PC with modules I use , that perhaps would help me out so I don't have to keep collapsing the soft tube module and ones I don't use.  Having a blank PC would be so much easier .
