Increasing width and color of slider bars

Question

I've tried searching for this one and haven't come up with anything, so, at the risk of bringing up a topic that's been already answered somewhere else (please if so, tell me where) here goes:
I want to center images at higher magnifications. Just because you can put your cursor
on the IMAGE and use the scroll wheel to make it go up and down doesn't mean you can make the image go right and left at the same time. Personally, I'd like to continue to use the scroll wheel to zoom in and out (done in preferences, yes) and put the cursor on either the vertical and horizontal slider bars and use the wheel to move the image up or down or right or left. But if you've ever tried to place your cursor on these narrow-*** slider bars you know it's hell to hit those things very
easily because they are barely 1/4" wide--if that.
So the question remains: How can a user increase the width
of these narrow little bars? Is there a way to do this?
Also the color of the bars is very near the same color and value as the
area surrounding it, making it difficult to see. Is it possible to alter the
color of the bars to something more visible, like say, a brighter color and/or different value

Answer 1

"I entirely agree that the panel sliders are narrow. However, I find the panel sliders to be entirely unnecessary. As Ian suggested you can scroll with the mouse wheel."
Wolf, thanks for the reply. Perhaps it is a matter of my non-grasp of the terminology/nomenclature of the various parts of the photoshop
viewing area. What I am saying is that the slider bars on the right and the bottom of the panel (making the image go up and down and right and left respectively) are quite narrow and are the exact same color/value as the corresponding white background of most of my images, making this narrow bar difficult to see on a laptop 3' away and even more difficult to put the cursor on easily.
When you put your cursor on the image itself, I prefer to increase/decrease the magnification as set in preferences.
when you put your cursor on the slider bar on the right side and scroll with the mouse wheel, the image goes up and down. When you put your cursor on the bottom slider bar and scroll with the mouse wheel, the image moves right or left.
However, these aforesaid bars are so narrow that it's a pain in the a** to put the cursor on them to start with. Now, if these slider
bars could be made WIDER (and even perhaps a different color from the
area directly adjacent to it most of the time) it would be easier
to perform the tasks described above.
So I am simply trying to find out (because I have looked and looked) if perhaps these bars can be made wider. This is what Jeff was originally asking and represents to me an easier solution in that one has only to use one's mouse instead of using another hand and hitting shortcut keys and changing modes, etc.
I'm sorry if I'm not making this clear enough. Despite my poor grasp of descriptive english to make my question clear, I've been with P/S since version 3.0 and know about grid view, loupe view, etc. I just
wanted to find out if it were possible to widen the slider bars.
Thanks to you and Mr.McWilliams for trying to help.
