public class ERXAccessibleSubmitButton
extends ERXSubmitButton

Extends ERXSubmitButton with self-configuring accessibility hot key for the button. The default hot key is the first character. If that has been used by a button that appeared earlier on the page, the next choice is a capital character. If no non-conflicting capital characters are available, it selects the first character that does not conflict with an earlier button. If you want a different hot key, specify it in the accesskey binding. Note that if this conflicts with the self configured choice for a button that appeared earlier on the page that this conflict will not be resolved. You will have to define an accesskey for the conflicting button as well. If you don't want a hot key, bind accesskey to the empty string.

The default is to use the u (underline) element to identify the hot key in the button text. Use the accesskeyElement binding to specify a different element. The element can be decorated with other attributes, e.g.

 accesskeyElement = "span style='text-decoration: underline;'";
 

You can have this class replace WOSubmitButton via ERXPatcher.setClassForName(ERXAccessibleSubmitButton.class, "WOSubmitButton"); or use it explicitly by name in your WOD. It works best (does the most work for you) if you use it with the value attribute. No self configuring is done if there is any content between the open and close tags.
