[news.eclipse.platform] How to bind Tab in plugin.xml for an editor.

["Gary E. Barnes" <gebarnes@xxxxxxxxxx>]

How do I do what the Java editor does for the Tab key?

The Java editor binds Control-I to "Correct Indentation" and it binds Tab to a 
function that works almost the same if the cursor is in the whitespace at the 
start of a line.  But I can't find the Tab binding anywhere.  I can find the 
Control-I binding,

<extension point="org.eclipse.ui.bindings">
   <key sequence="M1+I"
        commandId="org.eclipse.jdt.ui.edit.text.java.indent"
        ......

But what is it binding to Tab and more importantly how is it doing it? 
There's nothing bound to Tab according to the Preferences>Keys page but it 
obviously is bound to something.  I would like to provide the same general 
functionality in my editor, but what goes into the plugin.xml file?
