Advancing worksheets w/ scroll wheel

I am trying to find a way to replicate the "ctrl+Page Up"/"ctrl+Page Down" using a modifier key and the scroll wheel on my mouse. I have spread sheets with far too many worksheet tabs that I want to move through quickly, and reducing the number of sheets is not an option. So is there any way I can customize it to do this without taking my hand off the mouse? I am currently using MS 2003 but my company will soon be upgrading to 2010, I guess, so tips for one or both are welcome. Thanks.

It's not that I am trying to navigate quickly to a specific worksheet and stay there, it's that I have to move back and forth a lot between, sometimes distant, worksheets... copy a value on worksheet #5 and paste it in worksheet #135; copy output from #135 and paste it in sheets #5, #45, #104, and #110. If, for example (and I know this doesn't work), I could hold alt and scroll my wheel and have it advance through the worksheets, I think I could save an hour out over every day I have to do this, and probably add a week to the lifespan of my OEM wrist. Thanks for the idea, but that unfortunately doesn't save me the repetitive mousing around that I am trying to avoid.
