A plug-in for Coda by Panic. http://panic.com/coda

Tabster maps Tab and Shift-Tab to Command-] and Command-[, which allows you to indent blocks of text using the Tab key and outdent them by using Shift-Tab. Users of other editors that use these key combinations for block indenting will find this makes switching to Coda a lot easier.

Currently requires Mac OS X 10.5 Leopard.
