Is there a hotkey or some way to scroll the track view without using the mouse to drag the slider?

In Premier track view where you do you edits you "zoom" to a certian level, you do not look at the entire sequence at once. The "view" you see is indicated by your zoom and this is represented by the size of the scroll bar, as well as the scrol bar position. I am not talking about the play position, but that scroll bar at the every bottom of the track view that controls your postion of your current view and the scale of the view.

Are there any hotkeys for this? I find now I am using larger resolution monitoes that I often miss click when tryingto drag it. Maybe I can assign the move of the bar left and right to the mouse wheel or something?

What I would like to know if it is possible...

1. Hotkey to scroll the postion of the track view. Maybe 2 sets of hotkeys, one a smaller increment and the other a larger one. I am NOT talking about the playhead.
2. Hotkeys to zoom in and out on the track view. Again, but aweosme if there was increments.
3. If these exists can I assign them to the mouse wheel? Maybe mouse wheel to scroll the track view alt+mouse wheel to zoom in and out?

Thanks!
