Here is a list of "Bill Gates' Top Ten Tricks for
Windows 3.1:" 

10) <Shift>+File-Exit (Hold shift, choose the File, Exit menu options)
    This will save your settings without having to exit Windows.
 9) Load PROGMAN.EXE in the Startup Group, and assign it a Short-cut key
    (in a PIF). This will allow you, in the middle of a windows
    application, to hit the short-cut key and either bring up the
    program manager, or to hit another short-cut and bring up another
    windows (or DOS) application that has a short-cut assigned to it.
 8) Drag a file from the file-manager into an open group in the
    program-manager. This will create an icon for that file, based on
    the windows-app that created it. You can then double-click that
    icon, and bring up the app with the file ...
 7) <Alt>-Double-mouse-click on an Icon, to bring up the 'File,
    Properties' menu option.
 6) <Alt>-Double-mouse-click inside an open group in the program-manager
    to bring up the 'File, New' menu option.
 5) <Alt><Esc> will make all 'background' icons appear.
 4) Select "Allow Close When Active" in a PIF to close a DOS Window with
    a double-mouse-click. (Windows will ask about exiting, and so on
    ...)
 3) Hold <Shift> when loading Windows to avoid anything in the startup
    group. (This does not affect LOAD= and RUN= in the WIN.INI file.)
 2) ^<Shift> when dragging a file from the file manager to an OLE Client
    to get a linked packaged object. I.e., with the file manager open,
    and, say, a WRITE document open, drag a .TXT file with ^<SHIFT> held
    down at the same time, into the WRITE document (from File Man). You
    will get a 'Notepad' icon, with the name of the .TXT file. If you
    double-click the icon, the notepad will be brought up, with the file
    open. Tricky, eh?
 1) Package the calculator inside WRITE (or any other OLE capable
    Application) to create a tool-bar effect. I.e., if you use the OLE
    Package (in the Accessories group) to package the calculator inside
    WRITE (as an example), you will see an icon for the calculator at
    the top of the document. If you double-click it, it will be brought
    up on screen.
