Under the File menu in the Main CECILIA window, choose Preferences...

A great many features of CECILIA can be customized to your liking in the Preferences window. QuickKeys, colors, and all your service applications are chosen there.  Some assumptions/defaults are made for you. Choosing the correct sound player is very important!

Linux Note:For the help mechanism to work properly on Linux, you will need to have a browser that responds to the Netscape-style command line flags "-remote openURL(file:)". Netscape and Mozilla work, but so should just about any Gecko-based browser (Galeon, Phoenix, etc.).

CECILIA uses three of the standard Csound environment variables directories in its operations:

        $SFDIR - where Csound writes soundfiles.
        $SADIR - where you keep your sound analysis files.
        $SSDIR - where you keep your library of sounds.
