[edit] Accessing Effects with Shortcuts
You can use CTRL + R (or COMMAND - R on a Mac) to repeat the last used effect with those last used parameters. Audacity does not yet allow use of shortcuts to access frequently or recently used effects, but external macro programs provide a solution. See Accessing Effects with Shortcuts in Navigating Effects.
[edit] Chains in Audacity Beta
Audacity Beta allows a chain of effects to be created and run as a batch process. Click File > Edit Chains... to create the chain. Click File > Apply Chain... to apply the chain to the current project, or to audio files. Chains can be applied to a selected track or region in the project, just as you can when running an individual effect. However, you cannot yet specify a region of audio for individual effects inside a chain. Therefore chains will always be applied to all of an audio file.
