FCKConfig.TabSpaces broken?

Continuing to answer my own questions:

I used this code in FCKeditor_OnComplete:

//
// Set up keyboard commands
//
var CTRL = 1000; // from fckconstants.js
var SHIFT = 2000;
var ALT = 4000;
editorInstance.KeystrokeHandler.SetKeystrokes([9, 'MyTab']);
editorInstance.Commands.RegisterCommand('MyTab', new CommandTab);
editorInstance.KeystrokeHandler.SetKeystrokes([SHIFT + 9, 'MyTabShift']);
editorInstance.Commands.RegisterCommand('MyTabShift', new CommandTabShift);

and created two command handlers like this:

//
// Tab command handler.
//
var CommandTab = function(){this.Name = 'MyTab';}
CommandTab.prototype.Execute = function()
{
// send a qooxdoo event - you can do whatever you want here
getParentWidget().createDispatchDataEvent("editor-tab", false); // shift key is up
}
//
// Shift tab command handler.
//
var CommandTabShift = function(){this.Name = 'AblingTabShift';}
CommandTabShift.prototype.Execute = function()
{
// send a qooxdoo event - you can do whatever you want here
getParentWidget().createDispatchDataEvent("editor-tab", true); // shift key is down
}

This successfully stops the insertion of three spaces in FF with the tab key, and means I can get reliable navigation in and out of the editor.
