Thanks to: http://adomas.org/javascript-mouse-wheel/ for some pointers.
Thanks to: Mathias Bank(http://www.mathias-bank.de) for a scope bug fix.
Thanks to: Seamus Leahy for adding deltaX and deltaY
Version: 3.0.6
Requires: 1.2.2+
Possible Additional Configuration:
If, when you hold shift, you scroll through previous pages / history
Go to about:config page in firefox and set the variable mousewheel.with_shift.action to 0
If it still doesn't work and you are using a linux distribution go to linux's settings > windows > modifier for modified click actions (something like that) and change it to something other than shift
Also if alt click to save isn't working on linux
Go to about:config and set browser.altClickSave to true
You may have to go in to linux window setting again to change alt key's action
I've been in this situation before so I added this comment
I did not write any of the script myself
