Buttonfly supports unique color specification of demo buttons, buttons that have
a layer below them and of the background. Typically the demo buttons are a different
shade. <BR>
<BR>
With the 6.3 release of Irix, buttonfly now plays sounds when the buttons tumble.
If desired, buttonfly can be run
<a target=diag href="http://localhost/cgi-bin/Demos/DEMO_execute.cgi?related=buttonfly&exe=buttonflyAudio">with audio</A> using an option flag (-a). <BR>
<BR>
<B>Left Mouse:</B> <BR>
Activates tumble mode of buttonfly - If a demo button, the demo will actually start. If
it's a "level" button (usually a different color) then the button will tumble forward and
display the next level of buttons.<BR>
<BR>
Clicking on the background will tumble the button level back to the previous level. <BR>
<BR>
<B>Middle Mouse:</B><BR>
Essentially the same as using Left Mouse, but the buttons
don't tumble.<BR>
<BR>
<B>Space-bar:</B><BR>
Pressing the space bar will toggle between a full-screen version of buttonfly
and the window version. The full-screen version is useful for
presentations to large audiences, where visibility is important. <BR>
