You can set the following preferences in the Help category of the Preferences window.
You can show, hide, or change the display of the heads-up display text that appears for certain tools.
For each of these three options, Maya displays online help locally.
Select the documentation language set Maya loads when you use the help. If you have another documentation language set installed you can click Other and type a language/dialect code in the Specify language box.
The code that you enter must match the documentation folder name. For example, if you have Korean documentation installed in <drive>:\Program Files\Autodesk\Maya2011\docs\Maya2011\ko_KR, you must type ko_KR exactly in the Specify language box. Otherwise, an error is returned.
Maya displays online help from the URL specified in the Remote URL box. This can be a help system on an accessible network drive.
