Wheel Here

Input devices greatly evolved along the years, and even though now devices are ruled by touch-enabled displays, the mouse and keyboard are still going to be around for a while. As far as the mouse is concerned, the wheel aids a lot in page navigation, and with the help of Wheel Here you don’t even need to place a window in focus.

Perks of portability

A cool advantage is that there’s no setup involved, which means it can be easily stored on a USB flash drive to carry around and use on other computers besides your own. Another consequence of portability in this regard is that system registry entries remain intact during use, so you don’t need to worry about affecting the target PC.
The application directly goes to the tray area on launch, with no popup or notification to let you know it’s there. It doesn’t really come with a main window, except for the set of controls which don’t really need to be changed from their default values, since they’re configured to properly serve.

Scroll without changing focus

With the application active you can use the mouse wheel to scroll through documents without having to select the target window, nor to change focus. It’s enough to move your pointer over the area of interest. However, you can choose some restrictions, such as to emulate scroll even though the scroll bar doesn’t move.
Unfortunately, there’s no built-in option with which to make the application run with Windows to be ready by the time you reach the desktop. Luckily, this minor inconvenience can be bypassed by adding a shortcut of the executable to the system Startup folder.

In conclusion

Taking everything into consideration, Wheel Here is a pretty practical application which greatly enhances navigation through multiple windows without having to switch focus. Portability provides the flexibility you need, quietly sitting in the tray area without disturbing any of your activities.
