The Integrated Development Environment (IDE) allows you to use mouse wheels to do the following:

Rolling the mouse wheel, without holding down the Ctrl or Shift keys, will scroll the active editor or message window.
Rolling the mouse wheel, while holding down the Ctrl key, will zoom the size of the text in the editor and message windows.
Rolling the mouse wheel, while holding down the Shift key, will change the active window.

NOTE: Mouse wheels are not supported in Windows 95.
