Tranport comment and Navigation question

Transport:
I was always nagging for the pause button and am happy it's here, however, the pause button is redundant because it does nothing more than what the play button does once play is in effect; that is, to pause. If the play button turned into a pause button after it was clicked, then it would make perfect logical sense. Kudos for the spacebar, shift spacebar, ctrl spacebar combinations!
 
Navigation:
I am generally a mouser but am finally getting into using kb shortcuts after all these years; Is there a scroll bar key combination/shortcut? I am on a project where I am editing podcasts and need to quickly scroll through dialog to edit points (not yet marked), the zoom shortcuts are incredible time savers, a scrolling shortcut would be as well.
 
Thanks for any tips.

Is there a toggle for this or a pane focus required? When I hit the left/right arrow buttons, I get the highlights in the track channel strip (Track View) to "scroll", such as Track Name, then Mute, Solo, Record, Input Echo etc...?

k, thanks.
