Textbox (Firefox Auto Complete)

This element is created by setting the type attribute of a textbox to 'autocomplete'. It is used to create a textbox with a popup containing a list of possible completions for what the user has started to type.

Firefox uses a different autocomplete mechanism that the Mozilla suite. The example below will create an autocomplete textbox which will search the user's history.

Example:

    <textbox type="autocomplete" autocompletesearch="history"/>

The textbox (Firefox Auto Complete) element implements the following interfaces:

nsIAccessibleProvider   nsIAutoCompleteInput   nsIDOMXULMenuListElement

accesskey

Type: character

This should be set to a letter that is used as a shortcut key. This letter should be one of the characters that appears in the label text for the textbox. This letter will typically be drawn underlined, although this behavior will be platform and theme specific. When the user presses ALT (or a similar key that varies on each platform) and the access key, the textbox will be activated from anywhere in the window. Although the value is case insensitive, a letter with the case matching the accesskey attribute will used if both cases exist in the label.

To enable the textbox, leave the attribute out entirely as opposed to setting the value to false.
