Thunderbird 3 Compact/Expunge Current Folder Shortcut

Using Keyconfig for creating shortcuts in Mozilla products has been around for a long time. With Thunderbird 3 I struggled with figuring out how to create a shortcut to compact/expunge the current folder. The examples that show up in a Google search tend to be the solution for compacting all the folders. This tends to be time consuming if you have even a moderate amount of email. The solution was provided here:

Adding a Compact Folder Button to Thunderbird 3.0

If you are familiar with Keyconfig the short answer, without visiting the site, is the following key command:

goDoCommand("button_compact")

This will compact and expunge the current folder.
