I spend about half of my time on the computer working in Linux and the other half of my time working in Windows. As such, I have picked up a few habits about the way I have my computer set up and the way I use my computer. One of the great features of Linux (also present on Macs, apparently) is the way the scroll wheel on the mouse works. I would love to see this functionality added to Windows.
Within Windows, if you have a window focused and you use the scroll wheel, that action is going to have a single action attached to it. It will almost always (except for a select few programs) scroll the window frame up and down. If you are working within Outlook, whichever frame of the window you are focused in will scroll up and down, no matter where the mouse pointer is located on the screen. That’s all the scroll wheel will do.
