 disable it either via the global or browser''s settings dialog,

 or by evaluating:

 Change the above template into real code;

 remove this comment.

 Then `accept'' either via the menu

 or via the keyboard (usually CMD-A).

 You do not need this template; you can also

 select any existing methods code, change it,

 and finally `accept''. The method will then be

 installed under the selector as defined in the

 actual text - no matter which method is selected

 in the browser.

 Or clear this text, type in the method from scratch

 and install it with `accept''.
